а - ( $9\frac{3}{50}- 5\frac{7}{25}$ ) (а= $7\frac{1}{2}$ )

$9\frac{3}{50}$ = 9*50+3 = $\frac{453}{50}$

$5\frac{7}{25}$ = 5*25+7 = $\frac{132}{25}$

$\frac{453}{50} - \frac{132}{25} = \frac{453-264}{50} = \frac{189}{50}$ = $3\frac{39}{50}$

$7\frac{1}{2}$ = $\frac{15}{2}$

= $3\frac{36}{50}$

$\frac{15}{2} - \frac{189}{50} = \frac{375-189}{50}= \frac{186}{50}$
