Question

divide the sum of -5/8 and 4/5 by their diffrence with working​

Answer 1

Answer:

-7/57

Step-by-step explanation:

Sum of -5/8 and 4/5

$\frac{ - 5}{8} + \frac{4}{5} \\ = \frac{ -25 + 32}{40} \\ = \frac{7}{40}$

Difference -5/8 and 4/5

$\frac{ - 5}{8} - \frac{4}{5} \\ = \frac{ - 25 - 32}{40} \\ = \frac{ - 57}{40}$

Divide the sum by difference, we get

$\frac{7}{40} \div \frac{ - 57}{40} \\ = \frac{7}{40} \times \frac{ - 40}{57} \\ = \frac{ - 7}{57}$
