Question

calcule as expressoes abaixo e simplifique o resultado quando possivel a) 1/2+ 3/2 B)4/6-1/6 c)3/4+1 d)2-2/3

Answer 1

Resposta:

a)

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

b)

$\frac{4}{6} - \frac{1}{6} = \frac{3}{6 } \\ \frac{3 \div 3}{6 \div 3} = \frac{1}{2}$

c)

$\frac{3}{4} + \frac{1}{1} \\ \frac{3}{4} + \frac{4}{4} = \frac{7}{4}$

d)

$\frac{2}{1} - \frac{2}{3} \\ \frac{6}{3} - \frac{2}{3} = \frac { 4}{3}$
