Patrick drank 3/4 liter of water Monday before jogging. He drank 4/5 liter of water after his jog. How much water did Patrick drink altogether? (Write fraction answers as a mixed number like this 2 1/2) He drank _____ liters. *

Answer 1

Answer: 1¹¹/₂₀ litres

Explanation:

The fractions need to be added.

Find a common multiple for them.

Common multiple = 20

Divide the multiple by the denominator of the fraction and multiply the numerator by the result you get:

`= (15 + 16)/(20) \\\\= (31)/(20) \\\\= 1(11)/(20)`

= 1¹¹/₂₀ litres
