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.

Step-by-step explanation:

Equation of direct proportion between two quantities x and y :

$\dfrac{x_1}{y_1}=\dfrac{x_2}{y_2}$

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

$\dfrac{4}{7}=\dfrac{x}{35}\\\\\Rightarrow\ x=\dfrac{35\times4}{7}\\\\\Rightarrow\ x=20$

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