Equivalent fractions

2. Check if two fractions are equivalent.

In order to check whether two fractions are equivalent or not, the easiest method is the one of crossing products.
We "cross-multiply" its terms.

The product of the numerator of a fraction by the denominator of the other must have the same value in both cases.

In this window a random fraction appears, you have to type another one and then click on the blue triangle to see the verification step by step.
