2/1-1/4=?
1/8-2/2=?
3/8-1/4=?
2/5-1/4=?
3/4-1/4=?

Answer 1

$\frac{2}{1} - \frac{1}{4} = \frac{8-1}{4} = \frac{7}{4}$

$\frac{1}{8} - \frac{2}{2} = \frac{2-16}{16} = \frac{-14}{16} = \frac{-7}{8}$

$\frac{3}{8} - \frac{1}{4} = \frac{12-8}{32} = \frac{4}{32} = \frac{1}{8}$

$\frac{2}{5} - \frac{1}{4} = \frac{8-5}{20} = \frac{3}{20}$
