Owen drank
12 of the distilled water in his distilled water bottle. He accidentally spilled
35 of the remaining distilled water. As a result, he had 40 mℓ of distilled water left in his distilled water bottle. How much distilled water did Owen have at first? Give your answer in mℓ.

Fraction of remaining distilled water left after Owen spilled some
= 1 -
12=
12The volume of the remaining distilled water is the combined repeated identity. Make the volume of remaining distilled water the same. LCM of 1 and 5 is 5.
Volume of water left = 2 u
2 u = 40
1 u = 40 ÷ 2 = 20
Total volume of water that Owen had at first
= 10 u
= 10 x 20
= 200 mℓ
Answer(s): 200 mℓ
