Question

Simplify:

\[\frac{3}{8} - \frac{- 2}{9} + \frac{- 5}{36}\]

Answer 1

\[\frac{3}{8} - \frac{- 2}{9} + \frac{- 5}{36}\]
\[\text{Taking the L . C . M .} \hspace{0.167em} \text{of the denominators:} \]
\[\frac{27}{72} - \frac{- 16}{72} + \frac{- 10}{72}\]
\[ = \frac{27 - ( - 16) + ( - 10)}{72}\]
\[ = \frac{27 + 16 - 10}{72}\]
\[ = \frac{33}{72}\]
\[ = \frac{11}{24}\]
