Divide 1 2/5 by 21.

I got 15 as the answer.
Answered by ~christina~
If that is 2/5

(2/5)/21 =

since 21 is actually 21/1
flip and multiply

(2/5)*(1/21)= 2/105= 0.01904
___________________________________
If it's

(12/5)/21= 0.1143

Please be more specific as to whether that is a #1 or 1 is part of the question because you put a space in between the 1 and 2/5 which would lead to different answers but not 15.

Then again it could have been a fraction with

1 2/5 = 7/5 if this is true...

(7/5)/21= 0.0666

Writing it differently can mean alot of things you see.

(1 2/5)/21 = (7/5)/21 = (7/5)x(1/21) =
1/15.

I just copied it as a decimal (I didn't copy all the 6's) but if I had used the fraction function I would have also gotten 1/15 which is the same.
