Question

1/2 divided by N equals 1/3
what is N?

Answer 1

1/2 divided by n = 1/3

Inverse operation

1/2 / n = 1/3
*n *n

1/3 reciprocal is 3/1

1/2 * 3/1 = n
3/2 = n

n = 1 and 1/2

Answer 2

You said that (1/2) / N = 1/3

Multiply each side by 'N' : (1/2) = 1/3 N

Multiply each side by 3 : 3/2 = N

or 1-1/2 = N .
