Question

Explain how using equivalent ratios is like adding fractions with unlike denominators?

Answer 1

Explanation:

Equivalent ratios are just like equivalent fractions and are used to compare relationships between numbers.

Using equivalent ratios is like adding fractions with unlike denominators because to make a sum of fractions the important thing is that the fractions have the same denominator. To add fractions with the same denominator, the numerators must be added leaving the same denominator.

Each fraction must be rewritten with a common denominator. The easiest way to find a common denominator is to multiply both numbers. Then, each numerator is multiplied by the number we have multiplied to the denominator, that is, if in the denominator you multiply by 3, in the numerator you multiply by 3. Finally, add the obtained numerators and keep the same denominator. Finally, if necessary, you simplify the fraction.

Answer 2

Equivalent ratios have different numbers but represent the same relationship. In this tutorial, you'll see how to find equivalent ratios by first writing the given ratio as a fraction. And it cannot be the same by adding tow fration with different ratio
