12The volume of the remaining distilled water is the combined repeated identity. Make the volume of remaining distilled water the same. LCM of 1 and 4 is 4.
Volume of water left = 3 u
3 u = 270
1 u = 270 ÷ 3 = 90
Total volume of water that Cole had at first
= 8 u
= 8 x 90
= 720 mℓ
Answer(s): 720 mℓ
