Multiply the whole number component of the mixed number by the denominator of the fraction. Add that product to the numerator of the fraction. Write that sum above the original denominator.
For example:
= Four and two-thirds
= 4 2/3
= ((4 * 3) + 2) / 3
= ((12) + 2) / 3
= 14 / 3

What is a subtracting mixed number?
Subtracting a mixed number is just subtracting fractions but with a whole number by a fraction. To subtract tun the mixed numbers into improper fractions and find the common denominator. Then you subtract the numerators.
When finding volume do you need improper fractions or mixed numbers?
To find a volume you usually need to multiply values together. When working with mixed numbers it is usually easier to convert them into improper fractions, do the calculations and convert any resulting improper fraction into a mixed number. So you don't need to use either format, it's just that improper fractions are easier to manipulate.
How do you find the sum of all fractions?
Make sure the denominators of all the fractions are common.Add all numerators.Reduce the final fraction to its simplest form.Convert improper fraction to mixed number if needed.
How do mixed numbers become improper fractions?
While mixed numbers are the natural choice for spoken English (and are therefore well-suited to the answers of word problems), they aren't generally the easiest fractions to compute with. In algebra, you will almost always prefer that your fractions not be mixed numbers. Instead, you will use "improper fractions", or fractions where the top number is bigger than the bottom number. The standard way to convert a mixed number to an improper fraction is to multiply the bottom number by the "regular" number, add in the top number, and then put this on top of the bottom number as a new fraction. For instance, to convert 11/2 to an improper fraction, you do the following:I multiplied the bottom 2 by the "regular" 1, and then added in the 1 from on top, getting 3. Then I put this 3 on top of the 2 from underneath.

Remember that a fraction is just division. Divide the top number by the bottom number. Whatever you get on top of the division symbol is your "regular" number. Whatever your remainder is, put that number on top of the number you divided by. (To convert to mixed numbers, don't use decimals. Just find the quotient and the remainder. Then stop.)Convert to a mixed number.First, I do the long division to find the whole-number part (being the quotient) and the remainder:Since the remainder is 1 and I'm dividing by 4, the fractional part will be 1/4.
How do you find the inverse of a mixed number?
change it to an improper fraction and then divide it
