Question

Resolva as expressões numéricas abaixo:

A) 1/3 + 5/6 + 4
B) 1/2 - 1/4 + 19/20
C)5- (1/3 + 5/6)
D) (5/6 - 3/4) + (1/3 - 1/4)

Answer 1

A) $\frac{1}{3} + \frac{5}{6} + 4 2 + 5 + 24 / 6 = 31/6$

B) $\frac{1}{2} - \frac{1}{4} + \frac{19}{20} 10 - 5+ 19/20 = 24/20$

C) $5- ( \frac{1}{3} + \frac{5}{6} ) 5- (2+5/6) 5 - 7/6 30-7/6 = 23/6$

D) $( \frac{5}{6} - \frac{3}{4} ) + ( \frac{1}{3} - \frac{1}{4} ) (10-9/12) + (4-3/12) (1/12) + (1/12) = 2/12 = 1/6$
