$2$ $color(red) 2$

$4 \frac{1}{2} = \frac{9}{2} and 2 \frac{1}{4} = \frac{9}{4} s o,$ $4 1/2 = 9/2 and 2 1/4 = 9/4 so,$

$= 4 \frac{1}{2} \div 2 \frac{1}{4}$ $=4 1/2 -: 2 1/4$

$= \frac{9}{2} \div \frac{9}{4}$ $= 9/2 -: 9/4$

$= \frac{9}{2} \times \frac{4}{9}$ $= 9/2 color(red)(xx 4/9$

notice how the denominator and numerator are switched and
the division replaced by multiplication

$= \frac{4}{2}$ $= 4/2$

Simplified

$= 2$ $= 2$
