There are () numbers that can be proportional to 1 / 3,1,9 / 100. Selection: a.0 B.1 C.2 D.3

There are () numbers that can be proportional to 1 / 3,1,9 / 100. Selection: a.0 B.1 C.2 D.3

1/3 *(27/100)=1*9/100
1*(3/100)=1/3 * 9/100
9/100 *(100/27)=1* 1/3
So there are three numbers that can be proportional to 1 / 3, 1, 9 / 100, they are 27 / 100, 3 / 100, 100 / 27
Option D is correct!
