Fraction of remaining water left after Eric spilled some
= 1 -
56=
16The volume of the remaining water is the combined repeated identity. Make the volume of remaining water the same. LCM of 1 and 4 is 4.
Volume of water left = 3 u
3 u = 450
1 u = 450 ÷ 3 = 150
Total volume of water that Eric had at first
= 24 u
= 24 x 150
= 3600 mℓ
Answer(s): 3600 mℓ
