Fraction of remaining distilled water left after Warren 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 = 3 u
3 u = 120
1 u = 120 ÷ 3 = 40
Total volume of water that Warren had at first
= 20 u
= 20 x 40
= 800 mℓ
Answer(s): 800 mℓ
