Fraction of remaining water left after Harry spilled some

13The volume of the remaining water is the combined repeated identity. Make the volume of remaining water the same. LCM of 1 and 3 is 3.
Volume of water left = 2 u
2 u = 60
1 u = 60 ÷ 2 = 30
Total volume of water that Harry had at first
= 9 u
= 9 x 30
= 270 mℓ
Answer(s): 270 mℓ
