convert it into a mixed number
Not necessarily.
divide the top number from the bottom, then times by 100.
No, nothing like it.
An IMPROPER FRaction can be converted to a mixed number/fraction. Here is an example 14/3 Divide the '3' into '14' . It will go '4 ' times with a remainder of '2'. So the '4' becomes the coefficient (big) number and the '2' is placed over the '3' to make a faction. So 14/3 = 4 2/3 Mixed number/fraction.
The number below the fraction bar in a fraction is the denominator. The number above the fraction bar is the numerator.
