Verified answer

Resposta:

1) 5/6 ÷ 4/5 = 5/6 × 5/4 = 25/32

2) 1/2 ÷ 3/4 = 1/2 × 4/3 = 4/6 = 2/3

3) 5/6 ÷ 8/9 = 5/6 × 9/8 = 45/48 = 15/16

4) 4/3 ÷ (-1/2) = 4/3 × (-2) = -8/3

5) 20/3 ÷ 2/3 = 20/3 × 3/2 = 60/6 = 10

6) (-5/2) ÷ (-1/2) = (-5/2) × (-2)= 10/2 = 5

7) 9/2 ÷ 4/5 = 9/2 × 5/4 = 45/8

8) 7/6 ÷ 3/2 = 7/6 × 2/3 = 14/18 = 7/9

Resposta:

1. 5/6÷4/5 = 5/6*5/4 = 25/24

2. 1/2÷3/4 = 1/2*4/3 = 4/6= 2/3

3. 5/6÷8/9=5/6*9/8= 45/48

4. 4/3÷(-1/2) = 4/3*(-2/1) = -8/3

5. 20/3÷2/3 = 20/3*3/2= 60/6= 10

6. (-5/2)÷(-1/2) = (-5/2)*(-2/1) = 10/2 = 5

7. 9/2÷4/5 = 9/2*5/4 = 45/8

8. 7/6÷3/2 = 7/6*2/3 = 14/18 = 7/9

O grande segredo da divisão de frações é manter a primeira e multiplicar pelo inverso da segunda ;)
