At first, a bucket contained
25 ℓ of water. Usha added another
13 ℓ of water into the bucket. Then she used
411 of all the water in the bucket. How much water did Usha use? Express your answer as a fraction in its simplest form.
Total volume of water in the bucket after Usha added more water into the bucket
= 25 + 13
= 615 + 515
= 1115 ℓ
11 u = 1115
1 u = 1115 ÷ 11 = 1115 x 111 = 115
Volume of water that Usha used
= 4 u
= 4 x 115
= 415 ℓ
Answer(s): 415 ℓ
