To write a decimal number in the form of a mixed number, we take the decimal part of the decimal number and divide it with its equivalent place value and then add it to the whole number part.
Thus, 3.01 can be converted to mixed number as follows:
3.01 = 3 + 0.01 = 3 + 1/100 = 3 1/100.
Therefore, 3.01 in mixed number is 3 1/100.
