Let the number be n. We have:
3 x 1/n = 9 x 1/6 (simplify)
3 x 1/n = 3 x 1/2, this is true only for n = 2.

The equasion would be 10x 1/j = 5x1/9 (if j equals some number) so the answer would be j=18.
It is: 1/100 times 100 = 1

Let's call the number x, then the reciprocal is 1/x 3/x is three times the reciprocal and that equals two. So 3/x=2 or3=2x and means x=3/2 Check it x=3/2 reciprocal is 2/3 and 3x 2/3=2.
The equasion would be 10x 1/j = 5x1/9 (if j equals some number) so the answer would be j=18.
2/x =16/20 16x = 40 x = 2.5
It is: 1/100 times 100 = 1
It is: 3/4 times 4/3 = 1 Any number times its reciprocal is 1.
