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 $\frac85$
