EDIT: I should have begun by defining some terms in case you are unfamiliar with them. In a fraction the denominator is the number below the line = 5. The numerator is the number above the line = 4 (the second 4) and anything before the fraction is a whole number (the first 4).
=======================================...
you convert the whole number (4) to a fraction by multiplying by the denominator.
ie 4 x 5 = 20.
then add this to the numerator (which was also 4).
so you have (20 + 4) /5
= 24/5
So you can use a calculator to complete this division or just work it out (4.8) and multiplying by 100 tells you the number as a percentage = 480%.
Do you mean the mixed fraction 4 and 4/5?
That is the number 4.8
If you want that as a percent of one, it will be 480%
Is this new math? When I was in high school, you had to put () to clarify your expression. That looks more like a date than a formula. If you program computers the same rules apply.
It could be 4/4 = 1 and 1/5 = .20 or 20 %
Or it could be 4/.8 (4/5 = .8) which is 5 or 500%
It if go to your calculator that you have in the 'Accessories' and enter it just like you state, the answer will calculator will assume the first and your answer will be 20% or .20.
What you really need to do is read your book if you mean 4 4/5 it is 4.80
20%
