Question

calculati 0,(3) +1/2×0,5​

Answer 1

Răspuns:

$\frac{3}{9} +\frac{1}{2} *\frac{5}{10} = \frac{1}{3} +\frac{5}{20} =\frac{20+15}{60} =\frac{35}{60} =\frac{7}{12}$

Explicație pas cu pas:

Amplifici cu 20 $\frac{1}{3}$ si cu 3 $\frac{5}{20}$

Simplifici cu 5 $\frac{35}{60}$

Answer 2

$\it0,(3)+\dfrac{1}{2}\cdot0,5=\dfrac{\ 3^{(3}}{9}+\dfrac{1}{2}\cdot\dfrac{1}{2}=\dfrac{^{4)}1}{\ 3}+\dfrac{^{3)}1}{\ 4} =\dfrac{4+3}{12}=\dfrac{7}{12}$
