studygurl14 · Answer

$\large 12\frac{3}{4}-40\%(12\frac{3}{4})$= the answer

studygurl14 · Answer

$\large 12\frac{3}{4}\rightarrow\frac{51}{4}$

$40\%\rightarrow\large\frac{40}{100}\rightarrow\frac{2}{5}$

$\large\frac{51}{4}-\frac{2}{5}(\frac{51}{4})$

studygurl14 · Answer

$\Large\frac{51}{4}-\frac{102}{20}$
$\Large\frac{51}{4}(\frac{5}{5})-\frac{102}{20}\rightarrow\frac{255}{20}-\frac{102}{20}=\tt the~answer$

studygurl14 · Answer

$\large 255 - 102=153$

$\Large\frac{153}{20}$, which simplifies into $\Large 7\frac{13}{20}$
