Question

a.4/8+2/4+1/8
b.3/5-3/8

Answer 1

Explicación paso a paso:

a.

$\frac{4}{8} + \frac{1}{8} + \frac{2}{4} \\ \frac{4 + 1}{8} + \frac{2}{4} \\ \frac{5}{8} + \frac{1}{2} \\ \frac{5 \times 2 + 8 \times 1}{8 \times 2} \\ \frac{18 }{16} = \frac{9}{8}$

b.

$\frac{3}{5} - \frac{3}{8} = \frac{8 \times 3 - 5 \times 3}{5 \times 8} = \frac{9}{40}$
