Question

find the difference of

-6/5 and -32/13

-7 and -4/7​

Answer 1

$\frac{ - 6}{5} - \frac{ - 32}{13}$

$LCM \: of \: 5 \: and \: 13 \: = 65$

$= \frac{( - 78) - ( - 160)}{65}$

$Applying \: Positive \: and \: Negative \: Rule$

$= \frac{ - 78 + 160}{65}$

$= \frac{82}{65}$

$- 7 - \frac{ - 4}{7}$

$= \frac{ - 7}{1} - \frac{ - 4}{7}$

$= \frac{( - 49) - ( - 4)}{7}$

$= \frac{ - 49 + 4}{7}$

$= \frac{ - 45}{7}$
