Fraction of remaining distilled water left after Sean 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 = 2 u
2 u = 140
1 u = 140 ÷ 2 = 70
Total volume of water that Sean had at first
= 20 u
= 20 x 70
= 1400 mℓ
Answer(s): 1400 mℓ
