Question

1/5*(1/2+1/3)=
Favor ​

Answer 1

Respuesta:

Explicación paso a paso:

a)

$\frac{1}{6}(\frac{1}{2} +\frac{1}{3} ) = \frac{1}{6}(\frac{3+2}{2.3} )= \frac{1}{6} .\frac{5}{6}$

$\frac{1}{6}(\frac{1}{2} +\frac{1}{3} ) = \frac{5}{36}$

b)

$\frac{1}{10}(\frac{2}{3} -\frac{3}{5} ) = \frac{1}{10}(\frac{2.5-3.3}{3.5} )= \frac{1}{10} .\frac{1}{15}$

$\frac{1}{10}(\frac{2}{3} -\frac{3}{5} ) = \frac{1}{150}$

c)

$(\frac{2}{3} -\frac{1}{2} ).(\frac{1}{3} -\frac{1}{5} )$

$(\frac{2.2-3.1}{3.2} )(\frac{1.5-3.1}{3.5} )$

$\frac{1}{6}$ . $\frac{2}{15}$ = $\frac{1}{45}$
