Question

Cálcule a FRAÇÃO (1/4 + 3) - (2/3 - 1/2)

Answer 1

$(\frac{1}{4}+3)-(\frac{2}{3}-\frac{1}{2})= \\ \\ \frac{1}{4}+3-\frac{2}{3}+\frac{1}{2}=\\ \\ \\ \frac{3+36-8+6}{12}=\frac{37}{12}$

Answer 2

(1/4 + 3) - (2/3 - 1/2) = (0,25 + 3) - (0,666... - 0,5) = (3,25) - (0,1666...) = agora, resolve essa parte! Espero ter ajudado
