Question

Jesse drank 3/4

liter of water Monday before going jogging. He drank 3/5
liter of water after his jog. How much water did Jesse drink altogether? Write your answer as a mixed number.

Answer 1

1 7/20

Explanation:

You want to add 3/4+3/5, but they need to have the same denominator. A common factor for 4 and 5 is twenty, so multiply 3/4 by 5/5 and 3/5 by 4/4. This will give you 15/20 + 12/20. You can add this to get 27/20, or 1 7/20 as a mixed number
