Resuelve

A 1_5/6+1/6 b 2/5+7/4-1/5*3/7

Answer 1

A1-5/6+1/6
1-$\frac{5}{6}$ + $\frac{1}{6}$
$\frac{6-5+1}{6}$$\frac{2}{6}$
$\frac{1}{3}$

B2/5+7/a-1/5*3/7
0.4+1.75-$\frac{1}{5}$*3*$\frac{1}{7}$
2.15-$\frac{3}{5}$*$\frac{1}{7}$
$\frac{215}{100}$-$\frac{3}{35}$
$\frac{43}{20}- \frac{3}{35}$
$\frac{301-12}{140} = \frac{289}{140}$
