Answer:

Step-by-step explanation:
Lets think about multiplication. What times 5 equals 20? (5x = 20)
It would be 4! (5 x 4 = 20)
So take the 4 and multiply it by the fraction.

Theres your answer :)
2 dimes = $0.20
2 dollars = $2.00
20 cents = 10% of 2 dollars
Set this up as a proportion.
400/15 = x/6
Solve for x.
