Fraction of remaining distilled water left after Archie 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 4 is 4.
Volume of water left = 1 u
1 u = 160
Total volume of water that Archie had at first
= 20 u
= 20 x 160
= 3200 mℓ
Answer(s): 3200 mℓ
