Question

$(\frac{1}{2}*\frac{2}{4}-\frac{1}{9})$

Answer 1

$\frac{1}{2}. \frac{2}{4} - \frac{1}{9} = \frac{1}{4} - \frac{1}{9} = \frac{9 - 4}{36} = \frac{5}{36}$

Answer 2

Resposta:

$\boxed{ \boxed{ \bf{ \frac{5}{36} } } }$

Explicação passo-a-passo:

$\frac{1}{2} \cdot \frac{2}{4} - \frac{1}{9}= \\ \\ \frac{1 \cdot2 }{2 \cdot4 } - \frac{1}{9} = \\ \\ \frac{2}{8} - \frac{1}{9} = \\ \\ \frac{72 \div 8 \cdot 2}{72} - \frac{72 \div 9 \cdot 1}{72} = \\ \\ \frac{18}{72} - \frac{8}{72} = \\ \\ \frac{18 - 8}{72} = \\ \\ \frac{ {10}^{ \div 2} }{ {72}^{ \div 2} } = \\ \\ \frac{5}{36}$
