Question

resolva a fração 2/3 + [1/5 - (1/6 + 1/4 ] × 1/3​

Answer 1

Resposta:

Explicação passo-a-passo:

$\frac{2}{3}+[\frac{1}{5}-(\frac{1}{6}+\frac{1}{4})]*\frac{1}{3}=\\\\ \frac{2}{3}+[\frac{1}{5}-(\frac{2+3}{12})]*\frac{1}{3}=\\\\\frac{2}{3}+[\frac{1}{5}-\frac{5}{12}]*\frac{1}{3}=\\\\\frac{2}{3}+[\frac{12-25}{60}]*\frac{1}{3}=\\\\\frac{2}{3}+(-\frac{13}{60})*\frac{1}{3}=\\\\\frac{2}{3}-\frac{13}{180}=\\\\\frac{120-13}{180}=\frac{107}{180}$

Answer 2

Explicação passo-a-passo:

2/3 + [1/5 - (1/6 + 1/4 ] × 1/3 =

2/3 + ( 1/5 - 1/6 - 1/4 ) ×1/3 =

$\frac{2}{3} + ( \frac{12 + 10 + 15}{60} ) \times \frac{1}{3}$

$\frac{2}{3} + \frac{37}{60} \times \frac{1}{3}$

$\frac{2}{3} + \frac{37}{180}$

$\frac{120 + 37}{180}$

$\frac{157}{180}$
