At first, a bucket contained
25 ℓ of water. Abi added another
14 ℓ of water into the bucket. Then she used
313 of all the water in the bucket. How much water did Abi use? Express your answer as a fraction in its simplest form.
Total volume of water in the bucket after Abi added more water into the bucket
= 25 + 14
= 820 + 520
= 1320 ℓ
13 u = 1320
1 u = 1320 ÷ 13 = 1320 x 113 = 120
Volume of water that Abi used
= 3 u
= 3 x 120
= 320 ℓ
Answer(s): 320 ℓ
