Question

(1/2-1/3)+(5/6-3/4)​

Answer 1

Resposta:

$( \frac{1}{2} - \frac{1}{3} ) + ( \frac{5}{6} - \frac{3}{4} ) = \\ ( \frac{(3 \times 1 ) - (2 \times 1)}{2 \times 3} ) + ( \frac{(5 \times 4) - (6 \times 3)}{6 \times 4} ) = \\ ( \frac{3 - 2}{6} ) + ( \frac{20 - 18}{24} ) = \\ ( \frac{1}{6} ) + ( \frac{2}{24} ) = \\ \frac{(1 \times 24) + (6 \times 2)}{24 \times 6} = \\ \frac{24 + 12}{144} = \\ \frac{36}{144} = \\ \frac{1}{4}$
