Ierofanga [76]
Answer:

x = 16

Explanations:

The given rquation is:

\frac{4}{7}=\text{ }\frac{x}{28}

Step 1: Cross multiply the equations. That is 28 multiplies 4 and 7 multiplies x:

28\text{   x   4    =     7   }\times\text{    x} 112 = 7x

Step 2: Divide both sides by 7

\frac{112}{7}=\text{ }\frac{7x}{7} 16 = x x = 16
