Fraction of remaining distilled water left after Bryan spilled some
= 1 -
34=
14The volume of the remaining distilled water is the combined repeated identity. Make the volume of remaining distilled water the same. LCM of 1 and 5 is 5.
Volume of water left = 4 u
4 u = 720
1 u = 720 ÷ 4 = 180
Total volume of water that Bryan had at first
= 20 u
= 20 x 180
= 3600 mℓ
Answer(s): 3600 mℓ
