8- {5 1/2 -(3 - 2 1/2)}

Answer 1

${\underline{{\red{|A}{\pink{n}{\color{blue}{s}{\color{gold}{w}{\color{aqua}{e}{\color{orange}{r}}}}}}}}}$

$\begin{gathered}\\ \bull\sf\longmapsto 8 - (5 \frac{1}{2} - (3 - 2 \frac{1}{2} ))\end{gathered}$

$\begin{gathered}\\ \bull\sf\longmapsto 8 - ( \frac{11}{2} - (3 - \frac{5}{2} ))\end{gathered}$

$\begin{gathered}\\ \bull\sf\longmapsto 8 - ( \frac{11}{2} - \frac{1}{2} )\end{gathered}$

$\begin{gathered}\\ \bull\sf\longmapsto 8-5 \end{gathered}$

$\begin{gathered}\\ \bull\sf\longmapsto 3\end{gathered}$

Steps:

• Convert the mixed number to an improper fraction
• Calculate the difference
• Subtract the fractions
• Subtract the numbers
