Fraction of remaining water left after Archie spilled some
= 1 -

14The volume of the remaining water is the combined repeated identity. Make the volume of remaining water the same. LCM of 1 and 5 is 5.
Volume of water left = 3 u
3 u = 180
1 u = 180 ÷ 3 = 60
Total volume of water that Archie had at first
= 20 u
= 20 x 60
= 1200 mℓ
Answer(s): 1200 mℓ
