Answer 1

Explicação passo-a-passo:

A) 16/24

16 ÷ 8 = 2

24 ÷ 8 = 3

16/24 = 2/3

B) 20/25

20 ÷ 5 = 4

25 ÷ 5 = 5

20/25 = 4/5

C) 27/81

27 ÷ 27 = 1

81 ÷ 27 = 3

27/81 = 1/3

D) 14/28

14 ÷ 14 = 1

28 ÷ 14 = 2

14/28 = 1/2

E) 18/24

18 ÷ 6 = 3

24 ÷ 6 = 4

18/24 = 3/4

F) 24/36

24 ÷ 12 = 2

36 ÷ 12 = 3

24/36 = 2/3

G) 7/21

7 ÷ 7 = 1

21 ÷ 7 = 3

7/21 = 1/3

H) 12/15

12 ÷ 3 = 4

15 ÷ 3 = 5

12/15 = 4/5

I) 15/40

15 ÷ 5 = 3

40 ÷ 5 = 8

15/40 = 3/8

J) 8/18

8 ÷ 2 = 4

18 ÷ 2 = 9

8/18 = 4/9

K) 9/12

9 ÷ 3 = 3

12 ÷ 3 = 4

9/12 = 3/4

Answer 2

A) 16/24= 8/12

B) 20/25= 4/5

C) 27/81= 3/9

D) 14/28= 7/14

E) 18/24 = 9/12

F) 24/36= 12/18

G) 7/21= 1/3

H) 12/15= 24/30 (se for só divisão e irrudivel)

I) 15/40= 3/8

J) 8/18= 16/36 (se for só divisão e irrudivel)

K) 9/12= 18/24 (se for só divisão e irrudivel)
