At first, a pail contained
27 ℓ of water. Erika added another
12 ℓ of water into the pail. Then she used
311 of all the water in the pail. How much water did Erika use? Express your answer as a fraction in its simplest form.
Total volume of water in the pail after Erika added more water into the pail
= 27 + 12
= 414 + 714
= 1114 ℓ
11 u = 1114
1 u = 1114 ÷ 11 = 1114 x 111 = 114
Volume of water that Erika used
= 3 u
= 3 x 114
= 314 ℓ
Answer(s): 314 ℓ
