Calculate: 2 (1)/(2)+(-3 (1)/(4))

Expression: $2 \frac{ 1 }{ 2 }+\left( -3 \frac{ 1 }{ 4 } \right)$

Convert the mixed number to an improper fraction

$\frac{ 5 }{ 2 }+\left( -3 \frac{ 1 }{ 4 } \right)$

When there is a $+$ in front of an expression in parentheses, the expression remains the same

$\frac{ 5 }{ 2 }-3 \frac{ 1 }{ 4 }$

Convert the mixed number to an improper fraction

$\frac{ 5 }{ 2 }-\frac{ 13 }{ 4 }$

Subtract the fractions

$\begin{align*}&-\frac{ 3 }{ 4 } \\&-0.75\end{align*}$
