Fraction of remaining water left after Charlie 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 = 1 u
1 u = 130
Total volume of water that Charlie had at first
= 24 u
= 24 x 130
= 3120 mℓ
Answer(s): 3120 mℓ
