Question

Can you answer this please with workings out

Answer 1

a) 640 ml

b) 40 ml

Explanation:

The ratio of lime to lemonade for the fizzy drink is 5 : 3 or as a fraction that would be

`\frac{\text{Lime juice}}{\text{Lemonade}}= (5)/(3)`

`\text{Therefore the ratio of lemonade to lime }\\\\ = \text{reciprocal of $ (5)/(3) $} }\\\\= (3)/(5)`

Part a)

For all 400 ml of lime juice we would need

`(3)/(5) * 400 \;ml = 3 * 80 = 240 \;ml`

Total amount of fizzy drink that can be maade
= amount of lime juice + amount of lemonade

= 400 + 240

= 640 ml

This is the answer to Part a)

Part b)

If Gianni has only 280 ml and is using all 400 ml of lime juice then the amount of lemonade used as calculated in part 1) is 240ml

That means the amount of lemonade left over = 280 - 240 = 40 ml
