Please help! I will give brainiest. You have 42 dimes and 30 quarters. You arrange the coins into groups that have the same ratio of dimes to quarters as the whole collection of coins. How many dimes are in a group that has 20 quarters? Complete the ratio table to solve the problem.

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
