Question

[(4)]^-1 -(5)^-1]of (5/8)^-1

Answer 1

Hey friend,
Here is the answer you were looking for:
$( {4}^{ - 1} - {5}^{ - 1} )of( { \frac{5}{8} )}^{ - 1} \\ \\ = ( \frac{1}{4} - \frac{1}{5} ) \times \frac{8}{5} \\ \\ = ( \frac{1 \times 5 - 1 \times 4}{20} ) \times \frac{8}{5} \\ \\ = (\frac{5 - 4}{20} ) \times \frac{8}{5} \\ \\ = \frac{1}{20} \times \frac{8}{5} \\ \\ = \frac{1}{5} \times \frac{2}{5} \\ \\ = \frac{2}{25}$


Hope this helps!!!
