Answer 1

a)

$\frac{3}{2} - \frac{2}{3} = \frac{9 - 4}{6} = \frac{5}{6}$

b)

$\frac{4}{6} - \frac{1}{3} = \frac{12 - 6}{18} = \frac{6}{18} = \frac{1}{3}$

c)

$\frac{5}{6} - \frac{3}{4} = \frac{20 - 18}{24} = \frac{2}{24} = \frac{1}{12}$

d)

$\frac{1}{2} - \frac{1}{3} = \frac{3 - 2}{6} = \frac{1}{6} \\ \frac{1}{6} - \frac{1}{6} = 0$

e)

$\frac{3}{2} - \frac{1}{19} = \frac{57 - 2}{38} = \frac{55}{38}$

f)

$\frac{5}{8} - \frac{2}{7} = \frac{35 - 16}{56} = \frac{19}{56}$
