Q 1.     Find the sum:

 

    (iii)     \frac{-9}{10}+\frac{22}{15}

Answers (1)

Given sum:\frac{-9}{10}+\frac{22}{15}

Taking the LCM of 10 and 15, we have 30

\Rightarrow \frac{-9\times3}{10\times3}+\frac{22\times2}{15\times2}

\Rightarrow \frac{-27}{30}+\frac{44}{30} = \frac{-27+44}{30} = \frac{17}{30}
