Question

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

Answer 1

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