Question

1/2-1/4
7/12-3/16
7/16-1/6
1-1/3​

Answer 1

1)

$\frac{1}{2}^{2} - \frac{1}{4} = \frac{2}{4} - \frac{1}{4} = \frac{1}{4}$

2)

$\frac{7}{12}^{4} - \frac{3}{16}^{3} = \frac{28}{48} - \frac{9}{48} = \frac{19}{48}$

3)

$\frac{7}{16}^{3} - \frac{1}{6}^{8} = \frac{21}{48} - \frac{8}{48} = \frac{13}{48}$

4)

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