Question

Olá quanto é
4/6-1/2+1/3

Answer 1

Explicação passo-a-passo:

$\sf \dfrac{4}{6}-\dfrac{1}{2}+\dfrac{1}{3}$

$\sf mmc(2,3,6)=6$

$\sf \dfrac{4}{6}-\dfrac{1}{2}+\dfrac{1}{3}$

$\sf =\dfrac{4\cdot1-1\cdot3+1\cdot2}{6}$

$\sf =\dfrac{4-3+2}{6}$

$\sf =\dfrac{3}{6}$

$\sf =\dfrac{3\div3}{6\div3}$

$\sf =\large\red{\dfrac{1}{2}}$

Answer 2

Olá,

$\frac{4}{6} - \frac{1}{2} + \frac{1}{3} \\ = \frac{4}{6} - \frac{1}{2} . \frac{3}{3} + \frac{1}{3} . \frac{2}{2} \\ = \frac{4}{6} - \frac{3}{6} + \frac{2}{6} \\ = \frac{4 - 3 + 2}{6} \\ = \frac{3}{6} \\ = \frac{3 \div 3}{6 \div 3} \\ = \frac{1}{2}$
