d) 1/2 + 1/7 + 5/7=

​

Answer 1

a) 5/3 + 1/6

$= \frac{10 + 1}{6}$

$= \frac{11}{6}$

b) 3/5 + 2/7

$= \frac{21 + 10}{35}$

$= \frac{31}{35}$

c) 1/4 + 2/3 + 1/2

$= \frac{3 + 8 + 6}{12}$

$= \frac{17}{12}$

d) 1/2 + 1/7 + 5/7

$= \frac{7 + 2 + 10}{14}$

$= \frac{19}{14}$

Answer 2

Explicação passo-a-passo:

a) 5/3+1/6 m.m.c=6

(10+1)/6=11/6

b) 3/5+2/7 m.m.c=35

(21+10)/35= 31/35

c) 1/4+2/3+1/2 m.mc =12

(3+8+6)/12=17/12

d) 1/2+1/7+5/7 m.m.c =14

(7+2+10)/14=19/14
