Learn how to order fractions

Let's learn on ordering fractions in today's learning. Ordering fractions is nothing but arranging fractions from smaller to greater or greater to smaller.

Starting with the best let's know what is a fraction. A fraction is a rational number composed of a numerator and a denominator. In a series of fractions, when the fractions are with similar denominators, it can be order according to the value of the numerator. But when the denominators are different, LCM has to be found out and thus a common denominator should be taken. There after the ordering is done.

For more help, avail to an online tutor and get your required help. Not just fractions but you also can avail to geometry tutors for geometry help.

Next time we will learn some other concept, till then enjoy practicing problems based on ordering fractions. Also do post your feed backs.

SQUARE ROOT

The study of Square roots comes under Arithmetic under Math. Square roots are the calculation of the number when multiplied with itself would result in the number.
For example: Square root of 4 is 2 as 2*2 =4
Square root of 25 is 5 as 5*5 =25

The Square root symbol is used for notation of the calculation of the square root of a number. The Square root symbol is 'v' shaped with the right arm being longer and over the number whose root is to be calculated.

The numbers can be of two types:

• Perfect squares
• Imperfect squares

Perfect squares often result in a whole number as an answer. Like square root of 64 is 8. (8*8)
Imperfect squares have fractional or decimal values as the answers. Like square root of 3 is 1.73.

Introduction to Related Rate Issues & solutions

The study of rates of change is called calculus. Related rates of issues in which rates of change are related by means of differentiation (The process of finding a derivative).

Standard example issues include water dripping from a cone - formed tank as well as a man’s shadow lengthening as they walks away from a street lamp. Calculus related rates issues are used to finding the rates of the changes of the two variables respect to time.

Example: A boy as well as a girl start from the same point. The boy walks S70o E at 2.6 m/sec. The girl walks south at 3.2 m/sec. At what rate is the distance between the boy & girl changing after 45 minutes?

Solution:

Let x be the distance the boy has travelled, y the distance the girl has travelled & z the distance between the boy & the girl. looking for math homework solver

Speed of the girl, (dx/dt) = 2.6 m/sec & the speed of the girl, (dy/dt) = 3.2 m/sec. The rate of change of the distance between the boy & girl is (dz/dt) after 45 minutes have passed. After t seconds, the distance boy has travelled is 2.6t while the girl’s distance is 3.2t.

So after 2700 seconds or 45 minutes, the boy’s distance is x = 2.6(2700) = 7020m & the girl’s distance y = 3.2(2700) = 8640m.

Introduction about two dimensional shape:

A two-dimensional shape is known as the “regular" each of its faces is the similar length and each of its angles is the similar angle. Two dimensional shapes is also known as the plane surface or plane figure, and the line fragments or faces and the arcs all are placed in the same plane. The arc and face are called as the edges of the shape.

Two- Dimensional Shapes( Names)

The edges of the 1 dimensional shapes are placed in the plane are called as the two dimensional shape. These edges of the end points are called as either corners or vertices. Those points are called as 0-dimensional but they are placed in the plane so it is called the two dimensional.

Above shapes are known as plane shapes and shapes has the two dimensions they are length and width.

Brief Notes for Two Dimensional Shapes:

Square:

In square opposite faces are similar and each side has the same length. Square each angle is equal into 90 degree. In square all sides’ lengths are equal.

Triangle:

Triangle is the virtual types of geometry. It is a polygon which has the 3 vertices and three faces and those are line segments are known as triangle. Triangle is the two- dimensional shape with 3 side plane.

Parallelogram:

Parallelogram is one type of the quadrilaterals. Parallelogram opposite sides is parallel and equal in length. Parallelograms opposite angles are equal. Parallelogram has the equal contradictory faces and angles and the contradictory faces are similar properties of a parallelogram

Rhombus:

Rhombus has the equal length in all of its sides. Opposite sides are equal in parallelogram. And the diagonals angles are equal. Parallelogram diagonals are intersects at right angles.

Trapezium:

Any one pair of equal sides is parallel in the trapezium. If non-parallel pair of opposite sides is equal and it is called as isosceles trapezium. In isosceles trapezium it has the non- parallel faces and equal, the base angles of the trapezium is also equal.

Prime Numbers 1-100

Today let us see what are Prime Numbers and then list Prime Numbers 1-100

The property of being prime is called primality. Prime numbers give rise to various generalizations in other mathematical domains, mainly algebra, notably the notion of prime ideals.

What is a Prime Number

A prime number (or a prime) is a natural number that has exactly two distinct natural number divisors: 1 and itself. The smallest twenty-five prime numbers.

Below is the list of prime numbers to 100

There are 25 prime numbers between 1 and 100.

2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, and 97.

A natural number is called a prime or a prime number if it has exactly two distinct natural number divisors. Natural numbers greater than 1 that are not prime are called composite.

The Prime Number Calculator is a mathematics educational software, which facilitates to check whether a given number is a prime number or composite number.

CHORD OF A CIRCLE

A chord of a circle is a geometric line segment whose endpoints both lie on the circumference of the circle. A secant or a secant line is the line extension of a chord.

A chord is a lot like a secant, but where the secant is a line stretching to infinity in both directions, a chord is a line segment that only covers the part inside the circle. A chord that passes through the center of the circle is also a diameter of the circle.

The chord in circle that passes through the centre of a circle is known as the diameter. It turns out that a diameter of a circle is the longest chord of that circle since it passes through the center. A diameter satisfies the definition of a chord circle, however, a chord is not necessarily a diameter. This is because every diameter passes through the center of a circle, but some chords do not pass through the center. Thus, it can be stated, every diameter is a chord, but not every chord is a diameter.

PERCENT TO DECIMAL

The topic for today is percent to decimal,

A percent can be expressed using the percent symbol %. A percent is equivalent to a fraction with denominator 100. Although percentages are usually used to express numbers between zero and one, any dimensionless proportionality can be expressed as a percentage. The fundamental concept to remember when performing calculations with percentages is that the percent symbol can be treated as being equivalent to the pure number constant 1 / 100 = 0.01.

Calculating the conversion from percents to decimals is done with division. In this way you know how to work out percentages

Converting from a percent to a decimal is done by dividing the percentage value by 100.

For example, 10% is 10/100 = 0.10

67.5% is 67.5/100 = 0.675

A decimal number is a floating-point value that consists of a sign, a numeric value where each digit in the value ranges from 0 to 9, and a scaling factor that indicates the position of a floating decimal point that separates the integral and fractional parts of the numeric value. The decimal point is the most important part of a Decimal Number. It is exactly to the right of the Units position. Without it, we would be lost ... and not know what each position meant.
