Question

I don't understand what the question is apparently. I've tried for hours and I cannot figure out the process of answering a question like this! Would someone be able to break down the steps to understand and answer.

Answer 1

Explanation:

1) one half = 1 + 1/2

Required butter for a recipe = 2/3 c

Required butter for a half recipe =
`(2)/(3)*(1)/(2)=(1)/(3)`

Now , Required butter for the increased (1 1/2) recipe =
`(2)/(3)+(1)/(3)=(3)/(3)=1` c

2) Increased recipe by one third ⇒ 1 + 1/3

Required butter for a recipe = 4/5 c

Required butter for 1/3 of the recipe =
`(4)/(5)*(1)/(3)=(4)/(15)`

Now , Required butter for the increased (1 1/3) recipe is

`=(4)/(5)+(4)/(15)\\\\=(4*3)/(5*3)+(4)/(15)\\\\=(12)/(15)+(4)/(15)\\\\=(16)/(15)`

3) Increased recipe by one half = 1 + 1/2

Required butter for a recipe = 7/8 c

Required butter for 1/2 of the recipe =
`(7)/(8)*(1)/(2)=(7)/(16)`

Now , Required butter for the increased (1 1/2) recipe is

`=(7)/(8)+(7)/(16)\\\\=(7*2)/(8*2)+(7)/(16)\\\\=(14)/(16)+(7)/(16)\\\\=(21)/(16) \ c`
