Question

Sa se rezolve.... pas cu pas

a= 100
b=10

Answer 1

$(\frac{a+b}{2} )+(\frac{b+\frac{a}{2} }{3} )=$

$(\frac{100+10}{2} )+(\frac{10+\frac{100}{2} }{3} )=$

$\frac{110}{2} +\frac{10+50}{3} =$

$55+\frac{60}{3} =$

$55+20=75$

Answer 2

$\it a=100 \Rightarrow \dfrac{a}{2}=50$

Expresia dată devine:

$\it \dfrac{100+10}{2}+\dfrac{10+50}{3}=\dfrac{110}{2}+\dfrac{60}{3}=55+20=75$
