Two methods: (1) Convert the mixed fractions to improper fractions first. This is generally the easier method. (2) Use the distributive property. For example, 2 x 3 1/3 = 2 x (3 + 1/3) = 2 x 3 + 2 x 1/3 = 6 + 2/3 = 6 2/3.

How is multiplying mixed numbers different than multiplying fractions?
if you have mixed numbers you make them into improper fractions before you multiply
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).
When multiplying two mixed numbers what do you do first?
First you change them into improper fractions. Then you multiply the numerator and the denamanator straight across. ;)
How do you add mixed fractions with another mixed fraction?
You convert them both to improper fractions by multiplying the denominators by the whole number and then adding the numerator to it. This number goes in the numerator and the denominator stays the same. Then you do this for the other fraction, making sure that the denominators of each fraction are equivalent. Then add the fractions as normal.
Why do you change mixed numbers to improper fractions before multiplying and dividing?
Because common denominators allow adding and subtracting of numerators. Improper fractions also have simplified rules over mixed numbers when performing multiplication and division.

Why is it necessary to convert mixed fractions to improper fractions before multiplying or dividing?
Multiplying mixed fractions is very cumbersome and prone to errors. Therefore, it is prudent to convert them to improper fractions. Once that is done, you may simply find the product of all the numerators and divide that by the product of all the denominators. Then you convert back to a mixed number. And there are lots of tricks -- like "canceling out" -- that you can do to simplify the multiplication. Unfortunately, those techniques are very difficult to demonstrate here. It would not be even if it is not an improper fraction and that's why you have to convert

How is multiplying rational numbers like multiplying fractions and multiplying decimals?
Fractions and decimals are usually rational numbers. Besides, multiplying rational and irrational numbers is also similar.
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.
Why do you think it is helpful to convert mixed numbers into fractions before multiplying or dividing?
So that you can get your answer more faster and you don't need to do a lot of work
