We have two fractions, \dfrac{2}{5} 5 2 ​ start fraction, 2, divided by, 5, end fraction and \dfrac{3}{10} 10 3 ​ start fraction, 3, divided by, 10, end fraction, and we want to rewrite them so that they have a common denominator (and whole number numerators). What numbers could we use for the denominator? Choose 2 answers: Choose 2 answers: (Choice A) A 10 (Choice B) B 5 (Choice C) C 20 (Choice D) D 15

(Choice A) A 10

(Choice C) C 20

Step-by-step explanation:

Fraction 1: 2/5

Fraction 2: 3/10

rewrite them so that they have a common denominator (and whole number numerators

For both fractions to have a common denominator, find the lowest common multiple of both denominators

5 = 5, 10, 15, 20, 25, 30, 35, 40

10 = 10, 20, 30, 40

The two lowest common multiple of 5 an 10 is 10 and 20

Therefore, the answer is

(Choice A) A 10

(Choice C) C 20
