Question

on the average deepa drinks 4/5 of a 6 ounce glass of water in 2 4/5 hours. how many glasses of water does she drink in one hour? 

Answer 1

1 5/7 glasses

Explanation:

4/5 of 6 ounces is 24/5 ounces

24/5 ounces in 2 4/5 hours equals 'x' ounces in 1 hour

(24/5)÷(14/5) = x/1

cross-multiply:

24/5 = 14x/5

70x = 120

x = 12/7 or 1 5/7
