Fraction of remaining distilled water left after Riordan spilled some
= 1 -
45=
15The volume of the remaining distilled water is the combined repeated identity. Make the volume of remaining distilled water the same. LCM of 1 and 2 is 2.
Volume of water left = 1 u
1 u = 110
Total volume of water that Riordan had at first
= 10 u
= 10 x 110
= 1100 mℓ
Answer(s): 1100 mℓ
