Class 8th West Bengal - Mathematics 3. Rational Numbers

Answer :

Let x be the number to which when is multiplied, we shall get 1.

We need to find x.

So, formulate it into a mathematical equation using operators and numbers.

x is multiplied with can be written as,

Or,

Or,

Now, when x is multiplied with , we get 1. That is,

To solve for x, multiply -3 on both sides.

⇒ x = -3

Thus, we shall get 1 by multiplying -3 with .
