Question

a)
$3 \ - \frac{1}{8}$

б)
$7 \ - \frac{11}{30}$

в)
$4 \ \ - \frac{4}{9}$

г)
$8 \ - \frac{43}{108}$
​

Answer 1

а)

$3 - \frac{1}{8} = \frac{3}{1} - \frac{1}{8} = \frac{24}{8} - \frac{1}{8} = \frac{24 - 1}{8} = \frac{23}{8 } = 2\frac{7}{8}$

б)

$7 - \frac{11}{30 } = \frac{199}{30} = 6 \frac{19}{30}$

в)

$4 - \frac{4}{9} = \frac{32}{9} = 3 \frac{5}{9}$

г)

$8 - \frac{43}{108} = \frac{821}{108 } = 7 \frac{65}{108}$
