At first, a bucket contained
27 ℓ of water. Emily added another
12 ℓ of water into the bucket. Then she used
511 of all the water in the bucket. How much water did Emily use? Express your answer as a fraction in its simplest form.
Total volume of water in the bucket after Emily added more water into the bucket
= 27 + 12
= 414 + 714
= 1114 ℓ
11 u = 1114
1 u = 1114 ÷ 11 = 1114 x 111 = 114
Volume of water that Emily used
= 5 u
= 5 x 114
= 514 ℓ
Answer(s): 514 ℓ
