## What is a Rational Number?

The definition of a rational number is “A number which can be expressed in the form of p/q or fraction where p and q are integers and q ≠ 0 is a Rational Number.

************************************

**************************

### Examples of Rational Numbers

All the integers and decimal numberes can be expressed in the form of p/q or fraction of two integers. For example 0 = 0/1, 1 = 2/2, -2 = -4/2, 0.5 = ½, 1.25 = 5/4, 0.3333… = 1/3 etc. Therefore, 0, 1, -2, 0.5, 1.25, 0.3333… etc. are some examples of rational numbers

Rational numbers include all the integers on a number line along with the fractions between integers. Look at the number line given below.

The set of rational numbers is denoted by Q.

Q = {… -1, …, -¾, …, -½, …, -¼, …, 0, …, ¼, …, ½, …, ¾, …, 1, …}

Note:

-      There are infinitely many rational numbers between any two integers.

-      There are infinitely many rational numbers between any two rational numbers.

## What is Integer?

The definition of integer is “Any counting number whether it is negative(-), positive(+) or zero(0) is an integer.”

The set of integers is an infinite set from both the sides and it is denoted by Z.

Z = {…… -5, -4, - 3, -2, -1, 0, 1, 2, 3, 4, 5 ......}

### What are Prime and Composite Numbers?

A number which has only two factors is called a Prime Number and a number having more than two factors is called a Composite Number.

************************************

10 Math Problems officially announces the release of Quick Math Solver, an android APP on the Google Play Store for students around the world.

**************************

For example,

2 has only two factors 1 and 2, so 2 is a prime number.

3 has only two factors 1 and 3, so 3 is a prime number.

5 has only two factors 1 and 5, so 5 is a prime number.

etc. But,

4 has three factors 1, 2, and 4, so 4 is a composite number.

6 has four factors 1, 2, 3, and 6, so 6 is a composite number.

8 has four factors 1, 2, 4, and 8, so 8 is a composite number.

etc.

### What is composite number? Define with examples.

Answer: The definition of composite number: "A number which has more than two factors is called a composite number." Or, a number having more factors other than 1 and the number itself is called a composite number.

************************************

10 Math Problems officially announces the release of Quick Math Solver, an android APP on the Google Play Store for students around the world.

**************************

For example:

4 has a factor 2 other than 1 and 4, so 4 is a composite number.

6 has factors 2 and 3 other than 1 and 6, so 6 is a composite number.

8 has factors 2 and 4 other than 1 and 8, so 8 is a composite number.

9 has a factor 3 other than 1 and 3, so 9 is a composite number.

10 has factors 2 and 5 other than 1 and 10, so 10 is a composite number.

12 has factors 2, 3, 4, and 6 other than 1 and 12, so 12 is a composite number.

14 has factors 2 and 7 other than 1 and 14, so 14 is a composite number.

15 has factors 3 and 5 other than 1 and 15, so 15 is a composite number.

etc.

### Define prime number.

Answer: The definition of prime number: “A number which has only two factors is called a prime number. The two factors are 1 and the number itself.”

**************************

For example:

2 has its factors 1 and the number 2 itself. So, 2 is a prime number.

3 has its factors 1 and the number 3 itself. So, 3 is a prime number.

5 has its factors 1 and the number 5 itself. So, 5 is a prime number.

7 has its factors 1 and the number 7 itself. So, 7 is a prime number.

11 has its factors 1 and the number 11 itself. So, 11 is a prime number.

13 has its factors 1 and the number 13 itself. So, 13 is a prime number.

17 has its factors 1 and the number 17 itself. So, 17 is a prime number.

19 has its factors 1 and the number 19 itself. So, 19 is a prime number.

etc.

Enlargement (or reduction) is a transformation in which the size of an object is changed without changing its original shape. If the size of the object increase, we call it an enlargement and if the size of an object decrease, we call it a reduction.

************************************

10 Math Problems officially announces the release of Quick Math Solver, an android APP on the Google Play Store for students around the world.

**************************

The enlargement is made with the help of a fixed point called centre of enlargement and by the fixed ratio called scale factor i.e. the ratio of the corresponding sides of the image and object.

As enlargement changes the size of the object, it will have no real sense in case of a point.

The Translation is a transformation in which each point of the given object is displaced through definite distance and direction. The displacement is defined by a translation vector (a, b).

************************************

10 Math Problems officially announces the release of Quick Math Solver, an android APP on the Google Play Store for students around the world.

**************************

The following are the properties of translation:

1.   The object and the image under the translation are congruent.

2.   The lines joining any point of the object with its corresponding image are parallel and equal.

Rotation is a transformation in which each point on the object is rotated through an angle about a fixed point. The fixed point is called the centre of rotation and the angle is called the angle of rotation.

************************************

10 Math Problems officially announces the release of Quick Math Solver, an android APP on the Google Play Store for students around the world.

**************************

There are two types of rotations on the basis of directions:

1. Anticlockwise or Positive (+) rotation

2. Clockwise or Negative (–) rotation
