## Can you use a decimal as a denominator?

Casey,

Yes but remember that for example

1/0.5 = 1/(5/10) so that you have to take the reciprocal of 1/(5/10) which is

10/5 = 2

so the decimal should be converted into a fraction for simplicity

Hope that helps!

Another way to make it easier is to just multiply the top and bottom of the fraction by enough 10s to get the decimals to go away. So in the previous example multiply the numerator by ten and denominator by ten to get 10/5 which is easily reduced to 2.

Agreed!
