At first, a bucket contained
37 ℓ of water. Zara added another
12 ℓ of water into the bucket. Then she used
313 of all the water in the bucket. How much water did Zara use? Express your answer as a fraction in its simplest form.
Total volume of water in the bucket after Zara 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 Zara used
= 3 u
= 3 x 114
= 314 ℓ
Answer(s): 314 ℓ
