Question

Depois de observar a figura, qual resultado? 

a. 14/3
b. 5
c. 8/3
d. 5/2

Answer 1

$[ \frac{3}{5}:( \frac{2}{7}+ \frac{5}{14} ) ]*5\\\\\[ \frac{3}{5}:( \frac{(2*14)+(5*7)}{7*14} ) ]*5\\\\\[ \frac{3}{5}:( \frac{28+35}{98} ) ]*5\\\\\ [ \frac{3}{5}:( \frac{68}{98} ) ]*5\\\\\ [ \frac{3}{5}:[( \frac{9}{14} ) ]*5\\\\\ [\frac{3}{5}* \frac{14}{9}] *5\\\\\[[ \frac{42}{45} ]*5= \frac{42}{9}= \frac{14}{3}$
