Answer 1

b)

$\huge \frac{21}{24} {}^{(3} = \frac{7}{8} \\ \\ \huge\frac{12}{32} {}^{(4} = \frac{3}{8} \\ \\ \huge\frac{21}{24} - \frac{12}{32} = \frac{7}{8} - \frac{3}{8} = \\ \\ \huge = \frac{7 - 3}{8} = \frac{4}{8} {}^{(4} = \frac{1}{2}$

c)

$\huge \frac{2}{12} {}^{(2} = \frac{1}{6} \\ \\ \huge \frac{6}{36} {}^{(6} = \frac{1}{6}$

$\huge \frac{2}{12} - \frac{6}{36} = \frac{1}{6} - \frac{1}{6} = 0$
