Answer 1

Respuesta:

M = 2

Explicación paso a paso:

$M=\frac{\frac{3}{4}-\frac{1}{2}}{3+\frac{1}{2}}\div \frac{1}{28}\\\\M=\frac{\frac{3-(1*2)}{4}}{\frac{(2*3)+1}{2}}\div \frac{1}{28}\\\\M=\frac{\frac{3-2}{4}}{\frac{6+1}{2}}\div \frac{1}{28}\\\\M=\frac{\frac{1}{4}}{\frac{7}{2}}\div \frac{1}{28}\\\\M=\frac{2*1}{4*7}\div \frac{1}{28}\\\\M=\frac{2}{28}*\frac{28}{1}\\\\M=\frac{2*28}{28*1}\\\\M=2$
