Respuesta :

For this case we are going to define the following variables:
 x: number of cups of sugar
 y: number if apples
 We then have the following relationship:
 [tex] \frac{x}{y} = \frac{2}{16} [/tex]
 For 4 apples we have: [tex] \frac{x}{4} = \frac{2}{16} [/tex]
 From here, we clear the value of x.
 We have then:
 [tex]x = 4 \frac{2}{16} [/tex]
 [tex]x= \frac{8}{16} [/tex]
 [tex]x= \frac{1}{2} [/tex]
 Answer:
 you need 1/2 cups of sugar if you have 4 apples
