MCQ
$\frac{-7}{13}-\Big(\frac{-8}{15}\Big)=$
- A$-\frac{239}{195}$
- B$\frac{29}{195}$
- C$\frac{-29}{195}$
- ✓None of these.
$\frac{-7}{13}-\Big(\frac{-8}{15}\Big)$
$=\frac{-7}{13}+\frac{8}{15}$ $\Big[-\Big(\frac{-8}{15}\Big)=\frac{8}{15}\Big]$
$=\frac{-7\times15+8\times13}{195} (LCM$ of $13$ and $15 = 195)$
$=\frac{-105+104}{195}$
$=\frac{-1}{195}$
Hence, the correct answer is option $(d).$
