Question
What should be added to so as to $\frac{-7}{8}$ get $\frac{5}{9}?$
✓
Answer
The required nuber $=\frac{5}{9}-\Big(\frac{-7}{8}\Big)$
$=\frac{5}{9}+\frac{7}{8}$
$=\frac{40+63}{72}$ $(LCM$ of $9, 8 = 72)$ $=\frac{103}{72}$
$=\frac{5}{9}+\frac{7}{8}$
$=\frac{40+63}{72}$ $(LCM$ of $9, 8 = 72)$ $=\frac{103}{72}$
