To compare a decimal and a mixed number,
first convert, or change, one of the numbers so that we have either two decimals or two mixed numbers (or two fractions). Then, compare as usual.
First, let's write the mixed number as a decimal.
Now, compare 4.2 and 4.13.
As the tenth digit of 4.2 is greater than the tenth digit of 4.13,
4.2 > 4.13
