Question

subtract 3/4 from 1/3, -32/13 from 2,-7 from -4/7

Answer 1

1/3 - 3/4

$\frac{1}{3} - \frac{3}{4} \\ = \frac{4 - 9}{12} \\ = \frac{ - 5}{12} \\ = - \frac{5}{12}$

2 - -32/13

$2 - \frac{ - 32}{13} \\ = \frac{2}{1} - \frac{ - 32}{13} \\ = \frac{26 - ( - 32)}{13} \\ = \frac{26 + 32}{13} \\ = \frac{58}{13} \\ = 4 \frac{6}{13}$

-4/7 - -7

$\frac{ - 4}{7} - ( - 7) \\ = \frac{ - 4}{7} + 7 \\ = \frac{ - 4 + 49}{7} \\ = \frac{45}{7} \\ = 6 \frac{3}{7}$
