At first, a pot contained
15 ℓ of water. Xylia added another
13 ℓ of water into the pot. Then she used
48 of all the water in the pot. How much water did Xylia use? Express your answer as a fraction in its simplest form.
Total volume of water in the pot after Xylia added more water into the pot
= 15 + 13
= 315 + 515
= 815 ℓ
8 u = 815
1 u = 815 ÷ 8 = 815 x 18 = 115
Volume of water that Xylia used
= 4 u
= 4 x 115
= 415 ℓ
Answer(s): 415 ℓ
