Answer 3

\[-4 \frac{ 1 }{ 5 } - (-13 \frac{ 1 }{ 10 })\]

Answer 4

Turn into improper fractions first

\[\frac{ -21 }{ 5 } + \frac{ 131 }{ 10 }\]

multiply first fraction by 2/2

\[\frac{ -42 }{ 10 } + \frac{ 131 }{ 10 }\]

add
\[\frac{ -42 + 131 }{ 10 } = \frac{ 89 }{ 10 } = 8 \frac{ 9 }{ 10 }\]
