Question

x= (0,3*1/4) /0,1 y= (2*1/2) /3 qual o numero racional da fração x/y

Answer 1

 x = 3/10 * 1/4 = 3/40   /    1/10  =  3/4 

 y = 2/1 * 1/2 = 2/2 = 1  /   3  =   1/3

x/y = 3/4    /     1/3  =  1/4

resp é 1/4

Answer 2

x = (3/10 . 1/4) : 0,1

y = (2 . 1/2) : 3

 

x = (3.1)/(10.4) : 1/10

x = 3 / 40 . 10/1

x = 30/40 simplificando --> x = 3/4

 

y = (2.1)/2 . 1/3

y = 2/2 . 1/3

y = 2/6 --> simplificando --> y = 1/3

 

x/y = 3/4 / 1/3 = 3/4 . 3/1 = (3.3)/(4.1) = 9/4
