To rename mixed numbers in simplest form, simply multiply the denominator by the whole number and add the numerator, putting that answer over the original denominator. The answer results in a numerator that is larger than the denominator.
Changing mixed numbers to a simple fraction makes certain mathematical problems easier to complete. There are not many steps to the process and, once learned, it is quite easy to do.
Step 1: Multiply the denominator by the whole number
Multiply the denominator, or the number on the bottom of the fraction, by the whole number in the mixed number. For example, using the fraction 2 3/5, one multiplies 5 times 2 to get 10.
Step 2: Add the answer from Step 1 to the numerator
Take the answer from the multiplication step and add it to the numerator, or the number on top of the fraction. Using the 2 3/5 example, one adds 10 to 3, resulting in 13.
Step 3: Put the answer into fraction form
Take the final answer from step 2 and put it over the original denominator. Using the 2 3/5 example, one takes the answer from step 2, 13, and puts it over the original denominator of 5. This results in a final simple fraction of 13/5.

If the sign of the larger number is negative, then the result is a negative number. However, if the sign of the larger number is positive, then the result is a positive number.
Full Answer >An example of using an integer as an absolute value in real life is describing the distance, to or from something, using a whole number. For instance, someone would say they are 5 miles from Tucson or 5 miles past Tucson. In both cases, the person would be describing the distance as a positive number.
