Rational Numbers

We are familiar with the word number, we use it more than a hundred times in our day to day life, lets learn on different types of number that is rational number. Have you heard of the term rational number?

Below you will find the definition of the term rational number and following will be an example of a rational number.

Definition of a Rational number:- Numbers that are expressed in fraction is called as a rational number. Any number which can be expressed as quotient of two integers is called as rational number. The denominator is not equal to zero. Eg:- x/y here y is not equal to zero, it may be equal to 1. Every integers is a rational number.

Let us solve a problem on rational number below.

Problem No1:

Find a rational number between two rational numbers

To obtain the required number, add numerators and denominators as shown below:

Here we come to an end of this informative post on rational numbers, i will come up with many more interesting topic in future. Let me know how interesting you found this post. :-)

Solved problem on prime factorization

We been discussing on definitions and examples in most of my posts, today lets do something different. Today lets solve some problems on prime factorization.

1) Solve the prime factorization of 147

Answer:

3x3x7= 3x7²

2) Solve the prime factorization of 60

Answer: 2 × 3 × 5

3) Solve the prime factorization of 147.

Answer: 3 ×7 × 7 = 3 × 7²

^{4) Solve the prime factorization of 78}

^{Answer: 2} × ³ × ¹³

^{5) Solve the prime factorization of 330.}

Answer: 2 × 3 × 5 × 11

We have learn t how to factorize using small numbers and we have a few solved problems on prime factorization. This is a very useful topic for 6th and 7th grade, let me know your comments.
