At first, a bucket contained
35 ℓ of water. Winnie added another
14 ℓ of water into the bucket. Then she used
717 of all the water in the bucket. How much water did Winnie use? Express your answer as a fraction in its simplest form.
Total volume of water in the bucket after Winnie added more water into the bucket
= 35 + 14
= 1220 + 520
= 1720 ℓ
17 u = 1720
1 u = 1720 ÷ 17 = 1720 x 117 = 120
Volume of water that Winnie used
= 7 u
= 7 x 120
= 720 ℓ
Answer(s): 720 ℓ
