When working with mixed numbers it is almost always easier to convert them to improper fractions first, do the whatever (with the improper fraction just like an ordinary fraction) and convert any final improper fraction into a mixed number.
To convert a mixed number to an improper fraction, multiply the whole number by the denominator and add the numerator to form the new numerator and keep the denominator the same.
For example: 2 3/7 → (2x7+3)/7 = 17/7
To convert an improper fraction to a mixed number divide the numerator by the denominator to get a whole number quotient and a remainder. The whole number quotient is the whole number and the remainder is put as the numerator over the original denominator as the fraction.
For example: 17/7 → 17 ÷ 7 = 2 r 3 → 17/7 = 2 3/7

How do you write a whole number as imprper fractions?
You cannot: whole numbers and improper fractions are disjoint sets.
How do you change mixed numbers before multiplying improper fractions?
To convert a mixed number to an improper fraction, multiply the denominator by the whole number, add that total to the numerator and put the whole thing over the original denominator. 3 and 1/7 = 22/7
Do you change a mixed number into an improper number while adding and subtracting?
you do what makes sense given the numbers, if the fractions work out beautifully, you can just leave them as mixed numbers, otherwise it's best to keep them as improper fractions
How do you do mixed numbers?
turn them into improper fractions
How are proper and improper fractions different?
proper factions are fractions under a whole number improper fractions are Example: proper: 1/2 improper: 3/2
How do you turn a mixed number into a proper fraction?
Mixed numbers cannot be turned into proper fractions, but they can be made into improper fractions by multiplying the integer (# on the side) by the denominator (bottom), and then adding that number to the numerator (top).
Why convert mix number to improper fraction when multiplying mix number?
It's much easier to multiply fractions than it is to multiply mixed numbers. Try either one some time.
How to multiply mixed numbers?
First change the mixed numbers into improper fractions by multiplying the denominator and the whole number and add the product to the numerator in the mixed numbers and then multiply the numerators and the denominators and divide the numerator by the denominator of the product.
How do you multipy mixed numbers by mixed numbers?
Change each mixed fraction to an improper fraction. Do this by multiplying the denominator by the whole number next to the fraction and then adding the numerator to the product you get. Once you do this, multiply fractions normally.
How do you write a whole number as imprper fractions?
You cannot: whole numbers and improper fractions are disjoint sets.
How do you make a mixed number to a whole number?
Mixed numbers usually become improper fractions, not whole numbers.
How do you change mixed numbers before multiplying improper fractions?
To convert a mixed number to an improper fraction, multiply the denominator by the whole number, add that total to the numerator and put the whole thing over the original denominator. 3 and 1/7 = 22/7
What are the parts of fractions?
There are 3 Parts of fractions: 1:Improper Fractions Improper fractions are those fractions which numerator is greater than the denominator. 2:Proper Fractions Proper Fractions are those fractions which numerator is smaller than the denominator. 3:Mixed Numbers Mixed Numbers are those numbers which have a whole number and a part of fraction.
Do you change a mixed number into an improper number while adding and subtracting?

Why do you have to change a mixed number to an improper fraction before multiplying mixed numbers?
You don't.
How To Change A Number to an improper fraction?
Some numbers are improper fractions and some are not. For example, 1/2 or 0.5 is a number but not an improper fraction. And there is no way in which you can express it as an improper fraction.
How do you multiply improper fractions?
Multiplying improper fractions is just like multiplying proper fractions. You multiply the numerators (top number) of each fraction to come up with the numerator of the answer. The you multiply the denominators (bottom number) of both numbers to get the denominator of the answer.EX: 8/3 X 9/5= 72/15 or 24/5 (reduced)The next step in the equation is taking the improper fraction and converting it to a mixed number. You do this by dividing the numerator by the denominator. The whole number of the quotient becomes the whole number in the fraction, and the remainder becomes the numerator, which is over the denominator of the improper fractionEX: 24/5= 4 and 4/5; 24 divided by 5 = 4 with a remainder of 4.you just multiply as you would an number
