Let Mai's height  =  m

Let Jon's height  =  j

 

We want to find  \(\frac{m}{j}\)

 

\(\frac14\) of Mai's height - is equal to - \(\frac25\) of Jon's height  
\(\frac14\) of Mai's height = \(\frac25\) of Jon's height

 

 

 

\(\frac14\cdot m\) = \(\frac25\cdot j\)  

 

\(\frac14\cdot m\ =\ \frac25\cdot j\)

                             Multiply both sides of the equation by  4

\(m\ =\ \frac85\cdot j\)

                             Divide both sides of the equation by  j

\(\frac{m}{j}\ =\ \frac85\)

 

The ratio of  m  to  j  is  \(\frac85\)
