Question

Subtract:
$2\frac{3}{5}$ from $-\frac{3}{7}$.

Answer 1

We have to subtract $2\frac{3}{5}$ from $\frac{-3}{7}$.

$\frac{-3}{7}-2\frac{3}{5}$

$=\frac{-3}{7}-\frac{13}{5}$

LCM of $7$ and $5$ is $35$.

$=(\frac{-3}{7}\times \frac{5}{5})-(\frac{13}{5}\times \frac{7}{7})$

$=\frac{-15}{35}-\frac{91}{35}$

$=\frac{-15-91}{35}$

$=\frac{-106}{35}$

$\therefore \frac{-3}{7}-2\frac{3}{5}=\frac{-106}{35}$
