-28/45÷entre un numero fraccionario xx = 3/5

Answer 1

Explicación paso a paso:

$- \frac{28}{45} \div x = \frac{3}{5} \\ \\ - \frac{28}{45} = \frac{3}{5} \times x \\ \\ - \frac{28}{45} \div \frac{3}{5} = x \\ \\ - \frac{140}{135} = x \\ \\ - \frac{28}{27} = x \\ \\ x = - \frac{28}{27} \\ comprobación \\ - \frac{28}{45} \div ( - \frac{28}{27}) = \frac{3}{5} \\ \\ \frac{756}{1.260} = \frac{3}{5} \\ \\ \frac{3}{5} = \frac{3}{5}$
