How do you multiply a fraction and a whole number?
Multiply the fraction's numerator by the whole number, then reduce the improper fraction if necessary.Example : 3/4 x 6= (3 x 6) / 4 = 18/4 = 4 2/4 = 4 1/2
Why is the answer larger when you multiply a whole number by a whole number and smaller when you multiply a whole number by a proper fraction?
It is larger because the two whole numbers form a greater, larger number when multiplpied together. It is smaller when u multiply a whole number by a fraction because a fraction is a decimal and u get a smaller number when multiplying a number like 1/7 of 5
How do you multiply a fraction by a whole number without using a model or repeated addition?
Multiply the whole number times the numerator. Divide the product by the denominator.
How do you divide a whole number into a fraction?
Any whole number can be written over 1. To divide a fraction by a whole number, multiply that fraction by one over the whole number. 2/3 divided by 4 = 2/3 x 1/4
What algorithm makes sense for dividing any fraction by any whole number?
multiply by the reciprocal of the whole number
How do you devide whole numbers by a fraction?
Invert the fraction, and multiply it by the whole number.
Why do you end up with a smaller fraction when you multiply a whole number by a fraction?
You do not!3 is a whole number, 7/3 is a fraction.If you multiply the whole number by the fraction you get 3*(7/3) = 7, which is larger not smaller.
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?
What fraction and whole number with a product that is a whole number?
Any fraction can be multiplied by a whole number so that the product is a whole number. Simply multiply the fraction (in rational form) by its denominator.
When you multiply a whole number by a fraction is your result considered to be a multiple of the whole number?
No.
How do you multiply fraction by another fraction or a whole number?
turn both fractions into decimals and then multiply!
How do you multiply a whole number and a fraction in the simplest form?
Keep the same denominator, and multiply the numerator by the whole number.

How do i multiply a fraction by a whole number?
Multiply the numerator and the whole number. Put the total over the denominator. Simplify if possible.
How do you times a mixed fraction by a whole number?
As an example 2 3/5 X 7 First convert the mixed number to an improper fraqction Hence 2 3/5 = 13/5 Next we convert the '7' to an improper fraction by placing it over a trivial '1'. Hence '7' = '7/1'. Re-writing 13/5 x 7/1 We separate;y multiply the numerators together, and the denominators together. Hence 13/5 X 7/1 = 91/5 Finally we convert the improper fraction back to a mixed fraction by dividing by '5' , which will give an answer of '18' and a remainder of '1' Hence it is re-written as ' 18 1/5 '. The answer. NB Whenthe numbers become large , look to see if you can cancel down /reduce. So amending the above numbers slightly. 2 3/5 X 5 = > 13/5 X 5/1 In this case '5' is a common factor ; top & bottom'. so we cancel down by '5' Hence 13/1 X 1/1 proceeding as before. 13 / 1 = 13 The answer!!!!! These methods are good for any set of frqactional numbers.
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
