j) 4/5 : 1 1/2

Rápido por favor e para amanha

Answer 1

a) 4/5 : 2/3
4/5 . 3/2 = 12/10

b) 4/9 : 6/5
4/9 . 5/6 = 20/54 = 10/27

c) 1/4 : 7/3
1/4 . 3/7 = 3/28

d) 2/7 : 1/5 
2/7 . 5 = 10/7

e) 8/7 : 9/2 
8/7 . 2/9 = 16/63

f) 5 : 2/3 
5 . 3/2 = 15/2

g) 1/10 : 1/10
1/10 . 10/1 = 1

h) 6/7 : 5 
6/7 . 1/5 = 6/35

i) 3 1/2 : 4/7
3 1/2 / 4/7 = 7/2 . 7/4 = 49/8

j) 4/5 : 1 1/2
4/5 / 3/2 = 4/5 . 2/3 = 6/15 = 2/5

=)

Answer 2

segue o processo de uma divisão de fração você repete a primeira fração e Multiplica pelo inverso da segunda ok
vamos lá :

a)
4/5 : 2/3=>
4/5×3/2=>
12/10=>6/5

b)
4/9 : 6/5=>
4/9×5/6=>
20/54=>
10/27



c)
1/4 : 7/3=>
1/4×3/7=>
3/28


d)
2/7 : 1/5 =>
2/7×5/1=>
10/7


e)
8/7 : 9/2 =>
8/7×2/9=>
16/63



f)
5 /1 : 2/3 =>
5/1×3/2=>
15/2


g)
1/10 : 1/10=>
1/10×10/1=>
10/10=>
1


h)
6/7 : 5/1=>
6/7×1/5=>
6/35


i)

3 1/2 : 4/7=>
31/2×7/4=>
217/14

j)
4/5 : 1 1/2=>
4/5×2/11=>
8/55
