Cross canceling is a way to simplify or reduce fractions before multiplying them. For example, 2/4 x 1/6 can be reduced to 1/4 x 1/3 by cross canceling.

first you turn the mixed number into an improper fraction. then you cross simplify before you multiply. Note: cross-simplifying is pretty much dividing the num. of one fraction by the deno. of the other and then vice-versa. num: =numerator deno. =denominator

So that you can get your answer more faster and you don't need to do a lot of work

This has the effect of producing a denominator in the answer that has each of the original denominators as factors. You don't have to worry about simplifying the fractions before multiplying. Of course, you may have to simplify after multiplying. There's no way out.

In both cases, you may be able to cancel common factors, thus simplifying the expression.

That process helps to simplify your multiplication. If you have a problem such as (27/18)*4, instead of computing 27*4 then dividing that by 18 and simplifying, there is a much easier way to do it. Divide both top and bottom by 9 to get (3/2)*4. Cancel the 2 in the denominator and the 4 that is being multiplied to get 3*2. The resulting answer is 6. Notice how there were no big computations to deal with. This helps especially if you are computing all these numbers by hand or in your head.

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

if you have mixed numbers you make them into improper fractions before you multiply
