Question

divide the sum of 18/5 and -7/15 by their difference

Answer 1

sum of the rational numbers

$= \frac{18}{5} + \frac{ - 7}{15} \\ = \frac{54 - 7}{15} \\ = \frac{47}{15}$

And their difference

$\frac{18}{5} - \frac{ - 7}{15} \\ = \frac{54 + 7}{15} \\ = \frac{61}{15}$

Hence, the required quotient

$\frac{ \frac{47}{15} }{ \frac{61}{15} } \\ = \frac{47}{15} \times \frac{15}{61} \\ = \frac{47}{61}$

HOPE THIS COULD HELP!!!
