What if I tell you that mathematics is all around us? Wouldn’t it be fun to learn mathematics from things that we use, play, and see in our day-to-day life? In this blog, we’re bringing you an interesting lesson on Rational numbers from your mathematics and it is all fun to learn mathematics from the things we see on a day-to-day basis.

First, let us know the definition of rational number:

As per the example given in our book: A rational number is a number that can represent in the form of p/q of two integers such that the denominator q is not equal to zero.

Examples of Rational numbers are:

2/1, 3/1, -13/9, 4/5, etc. are known as rational numbers.

Positive Rational Numbers

As we know from now that the number in the form p/q where q is not equal to zero (q≠0) is known as rational numbers. Thus, in positive rational numbers, both numerator and denominator have the same sign.

For Example, if -9/-7 the minus signed will get canceled. As we know in the case of + sign, no sign is added.

Negative Rational Number

In a negative rational number, both numerator and denominator have two opposite signs.

For Example, 3/-7, -2/5, etc. As we know from BODMAS + multiply by – is Minus always.

If that wasn’t so fun to learn let us learn the rational number from the things around us.

Have you ever noticed when our grocery shopkeeper delivers us the item, he often writes in the form of a rational number, but where?

What about a half kilo (1/2) of sugar, haven’t you notice it was in the form of p/q?

A rational number is on our measuring scale, and likewise, it exists in the calculation we do in our everyday life.

And so, the rational number is all around us.

Our goal is to make mathematics and subject interesting for our students and therefore every week we come up with the new interesting topic for our readers.
