Question

soma das fracoes 1/4+2/3+1/2

Answer 1

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

Coloque todos os termos no mesmo denominador, que deve ser o MMC de 4, 3 e 2 = 12.

Logo temos $\frac{3 + 18 + 6}{12}$

Answer 2

$\frac{1}{4} + \frac{2}{3} + \frac{1}{2} = \frac{1+2+3}{12}$

$\frac{1}{4/3} \frac{2}{3/4} \frac{1}{2/6} \frac{1.3+2.4+1.6}{12}$

$\frac{3+8+6}{12} = \frac{17}{12}$
