The price of milk went from $5.25 to $2.10 per gallon. Find the ratio of the decrease in the price to the original price in lowest terms.

Answer 1

5.25-2.10 = 3.15

Decrease in Price: Original Price

3.15:5.25

This can be reduced by dividing the numerator and denominator by 1.05

3.15/1.05 : 5.25/1.05 =

3/5
