What is it called when you multiply the numerator and denominator by the same number?

What is it called when you multiply the numerator and denominator by the same number?

If you multiply both the numerator and denominator of a fraction by the same non-zero number, the fraction remains unchanged in value. Therefore, equivalent fractions can be created by multiplying (or dividing) the numerator and denominator by the same number. This number is referred to as a multiplier.

What is a fraction called when the numerator and denominator are the same?

We know from multiplication and division that when you multiply or divide a number by 1 you get the same number. We also know that when you have the same numerator and denominator in a fraction, it always equals 1. The two fractions have the same value and are equivalent.
