At first, a bucket contained
25 ℓ of water. Nicole added another
12 ℓ of water into the bucket. Then she used
79 of all the water in the bucket. How much water did Nicole use? Express your answer as a fraction in its simplest form.
Total volume of water in the bucket after Nicole added more water into the bucket
= 25 + 12
= 410 + 510
= 910 ℓ
9 u = 910
1 u = 910 ÷ 9 = 910 x 19 = 110
Volume of water that Nicole used
= 7 u
= 7 x 110
= 710 ℓ
Answer(s): 710 ℓ
