Answer 1

Given <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> $\frac{-12}{5}$ + <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> $\frac{43}{10}$

The LCM of 5 and 10 is 10

Consider $\frac{-12}{5}$ = $\frac{-12}{5}$ × $\frac{2}{2}$ = $\frac{-24}{10}$

$\frac{-12}{5}$ + $\frac{43}{10}$ = $\frac{-24}{10}$+ $\frac{43}{10}$

= $\frac{-24+43}{10}$

= $\frac{19}{10}$
