At first, a pot contained
34 ℓ of water. Wendy added another
15 ℓ of water into the pot. Then she used
719 of all the water in the pot. How much water did Wendy use? Express your answer as a fraction in its simplest form.
Total volume of water in the pot after Wendy added more water into the pot
= 34 + 15
= 1520 + 420
= 1920 ℓ
19 u = 1920
1 u = 1920 ÷ 19 = 1920 x 119 = 120
Volume of water that Wendy used
= 7 u
= 7 x 120
= 720 ℓ
Answer(s): 720 ℓ
