Fraction of remaining water left after Nick 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 5 is 5.
Volume of water left = 4 u
4 u = 120
1 u = 120 ÷ 4 = 30
Total volume of water that Nick had at first
= 30 u
= 30 x 30
= 900 mℓ
Answer(s): 900 mℓ
