ayuda doy coronita

Answer 1

Respuesta:

$a) \frac{1}{2} + \frac{3}{4} \div \frac{1}{8} = \frac{1}{2} + \frac{3}{4} \times 8 = \frac{1}{2} + 6 = 6 \frac{1}{2}$

$b)(1 - \frac{1}{2} ) \div (1 + \frac{1}{2} ) = ( \frac{2}{2} - \frac{1}{2} ) \div ( \frac{2}{2} + \frac{1}{2} ) = \frac{1}{2} \div \frac{3}{2} = \frac{1}{2} \times \frac{2}{3} = \frac{1}{3}$
