Answer 1

For this case we have the following data:

24 cookies require 1 1/2 cups of sugar. To know the amount of sugar that is required to make 36 cookies, we make a rule of three:

24 -----------> 1 1/2

36 -----------> x

Where x represents the amount of sugar required to make 36 cookies.

`x = ((36 *1(1)/(2)))/(24)`

`x = (36 * (1 + (1)/(2)))/(24)`

`x = (36 * (3)/(2))/(24)`

`x = (36 * 1.5)/(24)`

`x =(54)/(24)`

`x = 2.25`

`x = (2 + 0.25)`

`x = 2 (1)/(4)`

Thus,
`x = 2 (1)/(4)` cups of sugar are required to make 36 cookies.
