Answer:
Add the reciprocal of 3/2 to the reciprocal of - 3/7
Solution
Reciprocal of 3/2 = 2/3
Reciprocal of - 3/7 = - 7/3
Sum of 2/3 & - 7/3
\begin{gathered}( \frac{2}{3} ) + ( \frac{ - 7}{3} ) = \frac{2 + ( - 7)}{3} \\ = \frac{2 - 7}{3} \\ = \frac{ - 5}{3}\end{gathered}

8. Subtract the reciprocal of 5/14 from the product of - 3/10 & 2/15
Solution
Reciprocal of 5/14 = 14/5
Product of - 3/10 & 2/15
\begin{gathered}( \frac{ - 3}{10} ) \times ( \frac{2}{15} ) = ( \frac{ - 3}{15} ) \times ( \frac{2}{10} ) \\ = ( \frac{ - 1}{5} ) \times ( \frac{1}{5} ) \\ = \frac{ - 1}{25}\end{gathered}
