Answer 1

Siga a resolução da questão

$\sf{ \frac{1}{3} \times 0,222 + \frac{2}{3} \times 0,555 } \\ \\ \sf{ \frac{1}{\cancel{ 3}} \times \: \frac{\cancel{111}}{500} + \frac{2}{3} \times \frac{{111}}{200} } \\ \\ \sf{ \frac{37}{500} + \frac{2}{\cancel{3}} \times \frac{\cancel{111}}{200} } \\ \\ \sf{ \frac{37}{500} + \cancel{2} \times \frac{37}{\cancel{200}} } \\ \\ \sf{ \frac{37}{500} + \frac{37}{100} } \\ \\ \sf{ \frac{37}{500} + \frac{37 \times 5}{100 \times 5} } \\ \\ \sf{ \frac{37}{500} + \frac{185}{500} } \\ \\ \sf{ \frac{37 + 185}{500} } \\ \\ \sf{ \frac{222}{500} } \\ \\ \blue{\boxed{\sf{0,444}}} \\ \\ \therefore \: \sf{ \frac{1}{3} \times 0,222 + \frac{2}{3} \times 0,555 = {0,444} }$
