Question

A student traded four pieces of chocolate pour seven pieces of hard candy at this rate how many pieces of chocolate could be treated for 35 pieces of hard candy

Answer 1

Answer: 20 pieces of chocolate could be treated for 35 pieces of hard candy.

Explanation:

Equation of direct proportion between two quantities x and y :

`(x_1)/(y_1)=(x_2)/(y_2)`

Put
`x_1=4,\ y_1=7,\ y_2=35, x_2=x`

`(4)/(7)=(x)/(35)\\\\\Rightarrow\ x=(35*4)/(7)\\\\\Rightarrow\ x=20`

Hence, 20 pieces of chocolate could be treated for 35 pieces of hard candy.
