At first, a bucket contained
37 ℓ of water. Kathy added another
12 ℓ of water into the bucket. Then she used
513 of all the water in the bucket. How much water did Kathy use? Express your answer as a fraction in its simplest form.
Total volume of water in the bucket after Kathy added more water into the bucket
= 37 + 12
= 614 + 714
= 1314 ℓ
13 u = 1314
1 u = 1314 ÷ 13 = 1314 x 113 = 114
Volume of water that Kathy used
= 5 u
= 5 x 114
= 514 ℓ
Answer(s): 514 ℓ
