Question

1/2+3/8
______
3/4-5/12

Answer 1

Respuesta:

21/8

Explicación paso a paso:

$\frac{ \frac{1}{2} + \frac{3}{8} }{ \frac{3}{4} - \frac{5}{12} } = \frac{ \frac{4 + 3}{8} }{ \frac{9 - 5}{12} } \\ = \frac{ \frac{7}{8} }{ \frac{4}{12} } = \frac{ \frac{7}{8} }{ \frac{1}{3} } = \frac{7 \times 3}{8 \times 1} \\ = \frac{21}{8}$
