$\frac{1}{4} \: should \: be \: subtracted \: from \: 9 \: to \: get \: 7\frac{3}{5}$

To get the number that should be subtracted from 9 to get 7 3/4:-

$7\frac{3}{4}=\frac{7×4+3}{4}=\frac{31}{4}$

$\frac{9}{1}-\frac{31}{4}$

_____________________________

$\frac{9}{1}×\frac{4}{4}=\frac{32}{4}$

$\frac{31}{4}×\frac{1}{1}=\frac{31}{4}$

$\frac{32-31}{4}=\frac{1}{4}$
