You could also convert the mixed number to a decimal and multiply. 4 x 2.5 = 10
Both of those methods add extra work. It's simpler and faster to multiply the whole numbers (4 x 2), then the whole number and the fraction part of the mixed number (4 x 1/2) Adding those two products together gives you your answer. 8 + 2 = 10
First place the whole number over 1, and then convert the mixed number to an improper fraction. For example, your problem is 4 x 2 1/2.
Now your problem looks like 4/1 x 5/2. Next, multiply the numerators together and then multiply the denominators. 4 x 5 = 20, and 1 x 2 = 2, so you end up with 20/2, or 10 when you simplify.

How do you divide a mixed number by a whole number?
You change the mixed number to an improper fraction, multiply its denominator by the whole number. Then, if required, convert back to a mixed fraction.
How do you divide a mixed fraction by a whole number?
Multiply the denominator by the whole number, or divide the numerator by the whole number
How do you multiply a mixed fraction 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!
How do you divide a whole number by a mixed number?
To divide a whole number by a mixed number, you must first make the mixed number an improper fraction. You can do this by multiplying the denominator (the bottom number) by the whole number and adding the numerator (the top number) to the product. Once you have done this, take the reciprocal of the improper fraction (simply switch the two numbers around) and multiply it the whole number. Multiply everything out, make it a mixed number, and you're done. (Note: You may have to make the whole number a fraction to multiply it properly. To do this, simply place the whole number in the numerator and make the denominator 1.)
How do you change a mixed number to a whole number?
The majority of mixed numbers will convert to 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.
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 make a proper fraction into a mixed number?
To convert a proper fraction into a mixed number, divide the numerator by the denominator. The whole number part of the mixed number is the result of this division. The remainder becomes the new numerator, and the original denominator remains the same. Write the whole number, followed by the remainder over the original denominator to express the fraction in mixed number form.
How do you right a mixed number as a 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 mulitlpy mixed numbers and fraction?
Convert the mixed number into an improper fraction and then multiply like you normally would. To convert a mixed number into a fraction, take the whole number, multiply it by the denominator and then add the numerator. This value is your new numerator.
How do you change a whole number into a mixed number in quarters?
Multiply by 4: eg 13 = 52/4
How do you divide mixed number by whole number?
Convert the mixed number to an improper fraction and multiply it by the reciprocal of the whole number. 5 and 3/4 divided by 8 = 23/4 x 1/8
