Question

(8 7/12-2 5/8)-(3 7/12-1 1/3)

Answer 1

$8 \frac{7}{12} - 2 \frac{5}{8} = 8 \frac{14}{24} - 2 \frac{15}{24} = \\ 7 \frac{38}{24} - 2 \frac{15}{24} = 5 \frac{23}{24}$
$3 \frac{7}{12} - 1 \frac{1}{3} = 3 \frac{7}{12} - 1 \frac{4}{12} = 2 \frac{3}{12} = \\ 2 \frac{1}{4}$
$5 \frac{23}{24} - 2 \frac{1}{4} = 5 \frac{23}{24} - 2 \frac{6}{24} = 3 \frac{17}{24}$
