Bryan poured 988 mℓ of fruit punch into a glass, a cup and a bottle. The glass contained 4 times as much fruit punch as the cup. The bottle contained 123 mℓ of fruit punch.
- How much fruit punch did the cup contain?
- How much more fruit punch did the glass contain than the bottle?
(a)
Volume of fruit punch that a glass contained = 4 u
Volume of fruit punch that a cup contained = 1 u
Volume of fruit punch that a bottle contained = 123 mℓ
Total volume of fruit punch
= 4 u + 1 u + 123
= 5 u + 123
5 u + 123 = 988
5 u = 988 - 123
5 u = 865
1 u = 865 ÷ 5 = 173
Volume of fruit punch the cup contained
= 1 u
= 173 mℓ
(b)
Amount of fruit punch that the glass contained more than the bottle
= 4 u - 123
= (4 x 173) - 123
= 692 - 123
= 569 mℓ
Answer(s): (a) 173 mℓ; (b) 569 mℓ
