A mixed number is a number with a fraction and a whole number eg. 13/4.
To multiply fractions you multiply the numerators (top numbers) together and multiply the denominators (bottom numbers) together:
3/4 x 5/8 = 3x5/4x8
= 15/32
To multiply a mixed number by a fraction, convert the mixed number to an improper fraction by multiplying the whole number by the denominator and add the numerator to give the new numerator and put it over the original denominator. Then multiply the fractions as above and finally convert any improper fraction back to a mixed number by dividing the numerator by the denominator to get a quotient and a remainder; the quotient is the whole number and the remainder is the numerator over the original denominator.
eg 13/4 = 1x4+3/4 = 7/4 as an improper fraction.
eg 9/4 → 9 ÷ 4 = 2 r 1 → 9/4 = 21/4 as a mixed number.
13/4 x 5/8 = 7/4 x 5/8
= 7x5/4x8
= 35/32
= 13/32
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).

you have to turn them into improper fractions before you multiply them.
Fractions and decimals are usually rational numbers. Besides, multiplying rational and irrational numbers is also similar.

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.
