Which of the following pairs of fractions with a common denominator are equivalent to 1/4 and 2/5?a. 5/20, 8/20b. 1/20, 2/20c. 1/9, 2/9d. 5/20, 4/20

5 / 20 and 8 / 20 are pairs of fractions with a common denominator that are equivalent to 1/4 and 2/5

We are ask to find the equivalent of the pairs of fractions with a common denominator 1 /4 and 2 / 5.

The logic is to reduce by dividing the options with same numerator and denominator to get the equivalent of the fraction required.

Therefore,

5 / 20 and 8 / 20

5 / 20 ÷ 5  / 5 = 1 / 4

8 / 20 ÷ 4 / 4  = 2/5

Base on the answer you can see that when we reduced option A fractions, they are the same with the required fractions.

Therefore, 5 / 20 and 8 / 20 are pairs of fractions with a common denominator that are equivalent to 1/4 and 2/5
