Answer 1

a.

3/8 + 1/4

mmc(4 . 2) = 8

3/8 + 2/8

(3 + 2)/8

5/8

b.

6/11 + 2/7

mmc(11 . 7) = 77

42/77 + 22/77

(42 + 22)/77

64/77

c.

2/5 + 3/6

2/5 + 1/2

mmc(5 . 2) = 10

4/10 + 5/10

(4 + 5)/10

9/10

Answer 2

Explicação passo-a-passo:

$a) \frac{3}{8} + \frac{1}{4} = mmc = 8$

$\frac{3 + 2}{8 } = \frac{5}{8}$

$b) \frac{6}{11} + \frac{2}{7} = mmc = 77$

$\frac{42 + 22}{77} = \frac{64}{77}$

$c) \frac{2}{5} + \frac{3}{6} = mmc = 30$

$\frac{12 + 15}{30} = \frac{27}{30} = \frac{9}{10}$
