Question

d) 1 intreg 1/3 x 2 intregi 1/2 + 6 = ?

Answer 1

D) 1 intreg 1/3 x 2 intregi 1/2 + 6 = 
= 4/3 x 5/2 + 6 = 
= 10/3 + 6 =
=(10+18)/3=28/3=9 intregi si 1/3 

Answer 2

$1 \frac{1}{3} \times 2 \frac{1}{2} + 6$
$\frac{1 \times 3 + 1}{3} \times \frac{2 \times 2 + 1}{2} + 6$
$\frac{4}{3} \times \frac{5}{2} + 6$
**se simplifica 4 cu 2
$\frac{2}{3} \times 5 + 6$
$\frac{10}{3} + 6$
**amplifici 6 cu 3 ca sa aduci la numitor comun
$\frac{10 + 18}{3}$
$\frac{28}{3} = 9 \frac{1}{3}$
