Answer 1

Explanation:

How to determine whether the two given rational numbers are equal or not using cross multiplication?

We know there are many methods to determine the equality of two rational numbers but here we will learn the method of equality of two rational numbers using cross multiplication.

In this method, to determine the equality of two rational numbers a/b and c/d, we use the following result:

ab = cd

⇔ a × d = b × c

⇔ Numerator of first × Denominator of second = Denominator of first × Numerator of second
