1 2/5 divided by 21

Which is correct?

A. 21/1 x 5/7 = 105/7 =15

or

B. 1/21 x 7/5 = 7/105 / 7/7 = 1/15

Neither is correct. The answer is (2/5)/21 = 2/(5*21) = 2/105. Are you sure you copied the problem correctly?

1 2/5 divided by 21

sorry. I missed the "1" out front.

The answer is (7/5)/21 = 7/105

So, the answer is 15 or 1/5?

7/105 = 1/15

That is what I got.Good job DUDE.

I agree with drwis.... Are you sure you copied the problem correctly?

P.S. --- Is this your homework??
