Fraction of remaining milk left after Nick spilled some
= 1 -
45=
15The volume of the remaining milk is the combined repeated identity. Make the volume of remaining milk the same. LCM of 1 and 5 is 5.
Volume of water left = 3 u
3 u = 30
1 u = 30 ÷ 3 = 10
Total volume of water that Nick had at first
= 25 u
= 25 x 10
= 250 mℓ
Answer(s): 250 mℓ
