Question

Calculati:1 intreg-4/7;1 intreg-7/8;1 intreg-2/9;1 intreg-3/4;3 intreg-1/2;2 intreg-3/4;1 intreg-4/15;1 intreg-3/7.

Answer 1

$1- \frac{4}{7} = \frac{7-4}{7} = \frac{3}{7}$
$1- \frac{7}{8} = \frac{8-7}{8} = \frac{1}{8}$
$1- \frac{2}{9} = \frac{9-2}{9} = \frac{7}{9}$
$1- \frac{3}{4} = \frac{4-3}{4} = \frac{1}{4}$
$3- \frac{1}{2} = \frac{(3*2)-1}{2} = \frac{5}{2}$
$2- \frac{3}{4} = \frac{5}{4}$
$1- \frac{4}{15} = \frac{11}{15}$
$1- \frac{3}{7} = \frac{4}{3}$
