How do you find #1/10#th of a number?

Finding #1/10# of a number is the same as dividing it by #10#.

To find a tenth of something simply multiply it by #1/10# and then simplify. That will be a tenth of it:

#20# can be put over #1#, since anything divided by #1# is itself. So do that and multiply:

#1/10 xx 20/1 rarr 20/10 rarr 2#

Here are a couple more examples:

#1/10 xx 45/1 rarr 45/10 rarr 4.5#

#1/10 xx 896/1 rarr 896/10 rarr 89.6#

So as you can see, all you have to do is divida o número por 10 and you've found one tenth of it.
