Question

For every 5 coins Carmen gets she gives 2 to her brother frankie if carmen has 9 coins how many does frankie have

Answer 1

The answer is 6 because for every 5 coins she gets she gives 2.
Since: 5-2=3 (and 2 for her brother), then 3+5-2=6 (and 2 for her brother), then 6+5-2=9 (and 2 for her brother). Therefore totaling 6 coins for her brother. 

Answer 2

Lets write this as a ratio 1st.

For every 5 coins Carmen gives Frankie 2

5:2

9:?

5 - 2 = 3

So 3:2

9 ÷ 3 = 3

3 × 2 = 6

So, Caamen has 9 coins and Frankie has 6 coins.
