Question

1/2 + 1/3 + 1/4 simplificada pfv

Answer 1

Explicação passo-a-passo:

$\frac{1}{2} + \frac{1}{3} + \frac{1}{4}$

$= \frac{1 \times 6}{2 \times 6} + \frac{1 \times 4}{3 \times 4} + \frac{1 \times 3}{4 \times 3}$

$= \frac{6}{12} + \frac{4}{12} + \frac{3}{12}$

$= \frac{6 + 4 + 3}{12}$

$= \frac{13}{12}$

Answer 2

Explicação passo-a-passo:

$\frac{1}{2} + \frac{1}{3} + \frac{1}{4} \\ \frac{3}{6} + \frac{2}{6} + \frac{1}{4} \\ \frac{3 + 2}{6} + \frac{1}{4} \\ \frac{5}{6} + \frac{1}{4} \\ \frac{10}{12} + \frac{3}{12} \\ \frac{10 + 3}{12} = \frac{13}{12}$
