a)

$1 - \frac{4}{7} = \frac{7}{7}- \frac{4}{7} = \frac{7 - 4}{7} = \frac{3}{7}$

b)

$1 - \frac{7}{8} = \frac{8}{8} - \frac{7}{8} = \frac{8 - 7}{8} = \frac{1}{8}$

c)

$1 - \frac{2}{9} = \frac{9}{9} - \frac{2}{9} = \frac{9 - 2}{9} = \frac{7}{9}$

d)

$1 - \frac{3}{4} = \frac{4}{4} - \frac{3}{4} = \frac{4 - 3}{4} = \frac{1}{4}$

e)

$3 - \frac{1}{2} = \frac{ 6}{2} - \frac{1}{2} = \frac{6 - 1}{2} = \frac{5}{2}$

f)

$2 - \frac{3}{4} = \frac{8}{4} - \frac{3}{4} = \frac{8 - 3}{4} = \frac{5}{4}$

g)

$1 - \frac{4}{15} = \frac{15}{15} - \frac{4}{15} = \frac{15 - 4}{15} = \frac{11}{15}$

h)

$1 - \frac{3}{7} = \frac{7}{7} - \frac{3}{7} = \frac{7 - 3}{7} = \frac{4}{7}$
