What does it mean for two fractions to be equivalent? For two ratios to be equivalent?

Answer:Equivalent fractions and ratios mean that when simplified, they are the same one fraction or ratio. see examples below.Step-by-step explanation:For example, the fraction 1/2 is the same as 2/4 or 15/30 because when you simplify them, they are still 1/2. Therefore they are equivalent.For example, the ratio 1:2 is the same as 5:10 or 10:20 since when broken down they all come down to 1:2. Hence they are equivalent.Hope this answers your question.
