At first, a pot contained
15 ℓ of water. Jen added another
12 ℓ of water into the pot. Then she used
37 of all the water in the pot. How much water did Jen use? Express your answer as a fraction in its simplest form.
Total volume of water in the pot after Jen added more water into the pot
= 15 + 12
= 210 + 510
= 710 ℓ
7 u = 710
1 u = 710 ÷ 7 = 710 x 17 = 110
Volume of water that Jen used
= 3 u
= 3 x 110
= 310 ℓ
Answer(s): 310 ℓ
