Question

9/56-(7/15-5/12)*(3/14+1/2)

Answer 1

$frac{9}{56} - ( frac{7}{15} - frac{5}{12} ) times ( frac{3}{14} + frac{1}{2} ) = frac{9}{56} - frac{1}{20} times frac{5}{7} = frac{9}{56} - frac{1}{28} = frac{1}{8} \ 1) : frac{7}{15} - frac{5}{12} = frac{7 times 4 - 5 times 5}{60} = frac{28 - 25}{60} = frac{3}{60} = frac{1}{20} \ 2) frac{3}{14 } + frac{1}{2} = frac{3 + 7}{14} = frac{10}{14} = frac{5}{7} \ 3) : frac{1}{20} times frac{5}{7} = frac{5}{20 times 7} = frac{1}{4 times 7} = frac{1}{28} \ 4) : frac{9}{56} - frac{1}{28} = frac{9 - 2}{56} = frac{7}{56} = frac{1}{8}$
