the fractions have different denominators
No. The commutative and associative laws are valid for any real 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.
First you change them into improper fractions. Then you multiply the numerator and the denamanator straight across. ;)
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).
you have to turn them into improper fractions before you multiply them.

when you add mixed numbers you have a whole number but adding fraction does not.
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.
Because common denominators allow adding and subtracting of numerators. Improper fractions also have simplified rules over mixed numbers when performing multiplication and division.
Mixed fractions can't become whole numbers.
In case of Proper fractions the numerator is lesser than the denominator. Whereas in case of improper fractions and mixed fractions the numerator is greater than denominator.
