A mixed number is a combination of an integer and a proper fraction.
a proper fraction or a decimal
A mixed number.
a proper fraction
You cannot. By definition, a proper fraction is a number whose absolute value is between 0 and 1. There are no whole numbers between 0 and 1 so the number cannot be changed into a whole number. Also, since the absolute value is less than 1, it cannot be expressed as a mixed number.
851 is an integer - neither a proper fraction not a mixed number!
550 IS a whole number and so it cannot be expressed as a proper fraction.
It's simple really! When there is a whole number and a proper fraction it is a mixed number!
A proper fraction is when the number on the top is smaller than the number on the bottom like a half or two sixths
