More than that.

You need to multiply the whole number, the farctions AND cross multiply the whole numbers and the fractions. Then add together all the answers.

Thus,

23/4 * 56/7 = 2*5 + (3/4*6/7) + 2*6/7 + 3/4*5

Actually, it is far simpler to convert the mixed fractions to improper (top heavy) fractions, and then multiply the numerators together to give the numerator of the answer and multiply the denominators together to give the denominators of the answer.

How do you multiply mixed fractions by a whole number?

You would turn the mixed number into a fraction by multiplying the whole number(the one in the mixed fraction) by the denominator and then you add the numerator to the product. You would then put that number you get and out it over the denominator. For the other whole number, you would put it over one and multiply the two fractions!


When multiplying mixed numbers and fractions does changing the order of the factors change the product?

No. The commutative and associative laws are valid for any real numbers.


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).

How do you find the sum of two mixed numbers?

To find the sum of two mixed numbers, turn the mixed numbers into improper fractions (multiply the base with the denominator and add the numerator), then add the two fractions. To add the two fractions, find the LCD (lowest common denominator) and add the two numerators, but leave the denominators the same.

If doing it without a calculator, then convert each mixed fraction into a top-heavy equivalent fraction and then multiply as for fractions.


Adding mixed numbers with unlike denominators?

First convert the mixed numbers into "top heavy (or "improper) fractions". Now multiply each of the improper fractions by each other - this makes the denominators the same. Now you can add both the fractions together (and cancel down if necessary).


How do you convert mixed fractions into whole numbers?

Mixed fractions can't become whole numbers.


What do you do first with the mixed numbers before multiplying?

What you are to do is the mixed numeral is converted to a improper fraction. To do this just simply multiply the denominator with the whole number then add that with the numerator. With that number you end up with will be the numerator over whatever the denominator was. Then you can multiply the fractions.(I'm not a good explainer but i hoped i helped a bit)


How would you add two mixed numbers that contain unlike fractions?

you would convert the mixed numbers into fractions where the top number is greater than the bottom number, then multiply both the numerator and the denominator by a number that makes the denominators the same.


How do you change mixed numbers before multiplying improper fractions?

To convert a mixed number to an improper fraction, multiply the denominator by the whole number, add that total to the numerator and put the whole thing over the original denominator. 3 and 1/7 = 22/7
