Adam uses 100 mℓ of milk to make a drink.
It is
57 of the bottle of milk.
Give the answers in mℓ.
- How much milk does the bottle contain at first?
- How much milk is left?
(a)
Volume of milk that Adam uses = 5 u
Volume of the bottle of milk = 7 u
5 u = 100
1 u = 100 ÷ 5 = 20
Volume of milk that the bottle contains
= 7 u
= 7 x 20
= 140 mℓ
(b)
Volume of milk that is left
= 140 - 100
= 40 mℓ
Answer(s): (a) 140 mℓ ; (b) 40 mℓ
