Question

(3\4+1\2)+(2-1\4) qual o resultado deste polinômio?

Answer 1

$( \frac{3}{4} + \frac{1}{2} ) + ( \frac{2}{1} - \frac{1}{4} )$

$\frac{3}{4} + \frac{1}{2} \\ mmc = 4 \\ \frac{3}{4} + \frac{2}{4} = \frac{5}{4}$

$\frac{2}{1} - \frac{1}{4} \\ mmc = 4 \\ \frac{8}{4} - \frac{1}{4} = \frac{7}{4}$

$\frac{5}{4} - \frac{7}{4} = \frac{5 - 7}{4} = \frac{ - 2}{4}^{ \div 2} = \frac{ - 1}{2}$
