You have two fractions, 2/5 and 3/10, and you want to rewrite them so that they have the same denominator (and whole number numerators). what number(s) could you use for the denominator? choose the 2 answers that apply: a. 15 b.5 c.20 d.10 pls i will give brainliest and twenty points pls

D is the correct answer its the least common denominator!!

The answer to your question is C, and D. The way that you get this is by multiplying. To get 20, you multiply 2/5 by 4 to get 8/20, and you multiply 3/10 by 2 to get 6/20. To get 10 as a denominator for 2/5 you multiply by 2/5 to get 4/10, and you do not have to do anything to the 3/10 because the denominator is already 10. Then you just compare the numbers on the top to determine the larger fraction.
