Question

efetue as operaçoes com fraçoes fazendo as simplificaçoes quando possivel A) 2/3+5/6= B) 3/8+6/2= C) 8/5+6/7=

Answer 1

a) $\frac{2}{3} + \frac{5}{6} = \frac{4+5}{6} = \frac{9}{6} = \frac{3}{2}$

MMC de 3,6

3,6 | 2

3,3 | 3

1,1

MMC = 6

b) $\frac{3}{8} + \frac{6}{2} = \frac{3+24}{8} = \frac{27}{8}$

MMC de 8,2

8,2 | 2

4,1 | 2

2,1 | 2

1,1

MMC = 8

c) MMC de 5 e 7 = 5x7 = 35

$\frac{8}{5} + \frac{6}{7} = \frac{56+30}{35} = \frac{86}{35}$

Espero ter ajudado!
