É pra hoje

Answer 1

Explicação passo a passo:

para dividir duas frações multiplique a primeira pelo inverso de outra

(3/5)/(4/2) = (3/5)*(2/4) = 6/20 = 3/10

A)4/3÷8/2 = (4/3)*(2/8) = 8/24 = 1/3  

B)7/5÷3/2 = (7/5)*(2/3) = 14/15  

C)3/5÷8/5 = (3/5)*(5/8) = 3/8  

D)3/3÷1/9 = (3/3)*(9/1) = 9

E)2/1÷5/4 = (2/1)*(4/5) = 8/5  

F)5/8÷8/5 = (5/8)*(8/5) = 1

G)2/6÷6/7 = (2/6)*(7/6) = 14/36 = 7/18  

H)5/2÷8/3 = (5/2)*(3/8) = 15/16  

I)2/8÷7/4 = (2/8)*(4/7) = 1/7  

J)3/2÷4/7 = (3/2)*(7/4) = 21/8

K)5/2÷8/3 = (5/2)*(3/8) = 15/16
