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