At first, a bucket contained
34 ℓ of water. Jean added another
15 ℓ of water into the bucket. Then she used
319 of all the water in the bucket. How much water did Jean use? Express your answer as a fraction in its simplest form.
Total volume of water in the bucket after Jean added more water into the bucket
= 34 + 15
= 1520 + 420
= 1920 ℓ
19 u = 1920
1 u = 1920 ÷ 19 = 1920 x 119 = 120
Volume of water that Jean used
= 3 u
= 3 x 120
= 320 ℓ
Answer(s): 320 ℓ
