13The volume of the remaining distilled water is the combined repeated identity. Make the volume of remaining distilled water the same. LCM of 1 and 3 is 3.
Volume of water left = 2 u
2 u = 400
1 u = 400 ÷ 2 = 200
Total volume of water that Tim had at first
= 9 u
= 9 x 200
= 1800 mℓ
Answer(s): 1800 mℓ
