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.
Continue ReadingChanging 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.

Full Answer >To add improper fractions, determine if they have the same denominator, add the numerators, write the new numerator over the denominator, and simplify the answer, if necessary.
Full Answer >The lowest common denominator, or LCD, denotes the smallest number divisible by the denominators of every fraction in a set, whereas a least common multiple, or LCM, is the smallest multiple that two numbers have in common as products. Finding the LCD and LCM requires knowing prime factors of a number.
Full Answer >Rational numbers are any numbers that can be expressed by a fraction with integers in both the numerator and the denominator. The amount of time and paper it takes to put them into an increasing line depends on how many numbers there are and how big of a range they have.
