At first, a pail contained
35 ℓ of water. Joelle added another
13 ℓ of water into the pail. Then she used
714 of all the water in the pail. How much water did Joelle use? Express your answer as a fraction in its simplest form.
Total volume of water in the pail after Joelle added more water into the pail
= 35 + 13
= 915 + 515
= 1415 ℓ
14 u = 1415
1 u = 1415 ÷ 14 = 1415 x 114 = 115
Volume of water that Joelle used
= 7 u
= 7 x 115
= 715 ℓ
Answer(s): 715 ℓ
