how do i change 31 into a percentage?

Since 100% = 1, you can change any number to a % by multiplying it by 100%. In this case you'd get 3100%.

that's it! :)

by multiplying it by 100%
the answer will be 3100%

To change a number (whole or decimal) into a percentage, move the decimal point twice going to the right.

In this case, 31 will become 3100%

3,100%

Have you specified the question completely ? My first thought was to wonder " A percentage of WHAT ?" If you want 31 as a percentage of another number, then you multiply 31 by 100 and divide by the other number.

If you have found an answer which is 31 times the original quantity, then indeed 31 is 3100% of the original ( but notice that this is an INCREASE of only 3000% - that is, (31 - 1) x 100 )

31% ??

If half of something is 50%, and One Whole of something is 100%, then 31 wholes is 3100%

I hope this is what you are looking for!

31 out of what?

let us say 31 out of X

then (31/X) x 100 is the answer

31 x 100%
= 3100%

3,100%
