Answer 2

Resposta:

Explicação passo-a-passo:

a)

$|\frac{1}{2}-\frac{1}{3}|=|\frac{3-2}{6}|=|\frac{1}{6}|=\frac{1}{6}$

b)

$|(-\frac{1}{4}).\frac{2}{5})|=|-\frac{1}{10}|=\frac{1}{10}$

c)

$\frac{\frac{4}{3}.\frac{1}{3}-0,2}{\frac{2}{3}:\frac{1}{5}+\frac{2}{5}.\frac{1}{2}}=\frac{\frac{4}{9}-\frac{2}{10}}{\frac{2}{3}.\frac{5}{1}+\frac{1}{5}}=\frac{\frac{40-18}{90}}{\frac{10}{3}+\frac{1}{5}}=\frac{\frac{22}{90}}{\frac{50+3}{15}}=\frac{\frac{11}{45}}{\frac{53}{15}}=\frac{11}{45}.\frac{15}{53}=\frac{11.1}{3.53}=\frac{11}{159}$
