Question

daca a\7=5\3 , atunci numarul a+7\7 cu cat este egal?

Answer 1

a/7=5/3⇒a=35/3
a+7/7=(35/3+7)/7=(35/3+7)*1/7=56/3*1/7=8/3

Answer 2

$\frac{a}{7}= \frac{5}{3}\longrightarrow a= \frac{5\cdot7}{3}= \frac{35}{3}$

$\frac{ \frac{35}{3}+ \frac{21}{3} }{7}= \frac{ \frac{56}{3} }{7}= \frac{56}{3}\cdot \frac{1}{7}=\boxed{ \frac{8}{3} }$
