Some would suggest you just "Turn it into a decimal"
PROBLEM ALERT: Great for 1/4 where 1/4 = 0.25, but what about numbers like 1/3 where the decimal goes on forever 1/3 = 0.333333333333333 --> infinity
Why not follow the old school method?
Lets demonstrate with 2 x 3 3/4 x 5 1/3 = ?
First change all number to their fractional form 2=2/1 , 3 3/4 = 15/4 , 5 1/3 = 16/3
The equation is then 2/1 x 15/4 x 16/3 = ?
The top numbers (numerators) multiplied together are (2x15x16) = 480
The bottom numbers (denominators) multiplied together are (1x4x3) =12
Divide numerator answer by the denominator number to get the answer (240)/(12) = 40
The change it to decimals method would give 39.99975 if 1/3 is assumed to be 0.3333
The cleanest and easiest way is to change each one to an
improper fraction, and then multiply those.
First you have to convert the two numbers into fractions. Example:
13/8 X 3
Change 13/8 to a fraction = so now it's 11/8
Now change the whole number you are multiplying into a fraction = 3/1
Multiply the fractions you just converted = 11/8 X 3/1 = 33/8
You have 33 eights. If you want, now you can convert the 33 eights into 41/8

What do you do first with the mixed number before multiply?
Convert it to an improper fraction.
How do you multiply a mixed number with a whole number?
It helps if you change the mixed number into an improper fraction. After you do that you can multiply the improper fraction and the whole number. **hint if you put the whole number over 1 it will make it easier to multiply For example: Multiply 3 and 1/2 by 8 1) change 3 and 1/2 to an improper fraction. It would be 7/2 2) put 8 over one in a fraction. It would be 8/1 3) multiply 7/2 by 8/1 - first multiply the numerators 7 x 8= 56 - second multiply the denominators 2 x 1= 2 4) reduce your answer (56/2) It would be 28 And that is how you multiply a mixed number with a whole number
How do you convert each mixed number to an improper fraction?
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.
How do you write a mixed number as a improper fraction?
You take the whole number and multiply it by the denomonator and and your product to the numerator ,then you keep the same denomonator
How do you change a mixed number to an improper fracton?

How do you multiply fractions with whole numbers and mixed numbers?
The question is ambiguous. Do you want to know how to multiply a fraction by a whole number, as well as by a mixed number? Or are you asking how to multiply a whole number by a mixed number and express the product as a fraction? Or what?

How do you multiply a fraction bye a mixed fraction?
You would have to convert the mixed number into a fraction, or you could convert the fraction into a mixed number. The first one is easier in my opinion. For example: 2 3/4 is 11/4. Converting a fraction into a mixed number is just as easy but it is harder to multiply To multiply a mixed fraction by a fraction you will need to multiply the denominator (the bottom number of a fraction) by the whole number then add the numerator (the top number of a fraction) and that will be your new numerator. Then multiply the two fractions (straight across). Finally put you final answer in simplest form if needed.
