At first, a container contained
37 ℓ of water. Eva added another
12 ℓ of water into the container. Then she used
313 of all the water in the container. How much water did Eva use? Express your answer as a fraction in its simplest form.
Total volume of water in the container after Eva added more water into the container
= 37 + 12
= 614 + 714
= 1314 ℓ
13 u = 1314
1 u = 1314 ÷ 13 = 1314 x 113 = 114
Volume of water that Eva used
= 3 u
= 3 x 114
= 314 ℓ
Answer(s): 314 ℓ
