Best Answer

To multiply a fraction by a whole number, you must treat the whole number as a fraction by using 1 as the denominator (bottom number of the fraction). Example: 3/4 x 5 would be written 3/4 x 5/1. Then multiply the two numerators (top numbers) together for the numerator of the product fraction, and multiply the two denominators together for the denominator of the product. Thus 3x5 = 15 and 4x1 = 4 which would be the product 15/4. The next step is to convert the fraction to a mixed number by dividing the numerator by the denominator (15/4 = 3 r 3) which would be the final answer of 3-3/4.

Invert the fraction, and multiply it by the whole number.

No.

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.

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.

turn both fractions into decimals and then multiply!

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?

Keep the same denominator, and multiply the numerator by the whole number.

Convert the mixed number to an improper fraction and proceed with the multiplication.

Multiply the numerator and the whole number. Put the total over the denominator. Simplify if possible.

Multiply the denominator by the whole number, or divide the numerator by the whole number

Convert the mixed fraction to an improper fraction, multiply by the whole number, convert the answer back to a mixed fraction (if required).

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

Convert the mixed number to an improper fraction. Think of the whole number as being over one. Multiply them as you would any normal fractions.

If it is a rational fraction, you simply multiply its denominator by the whole number.

like this

(2/3)* 2

Multiply by the reciprocal.

No, you don't.

Multiply the fraction to the whole.

Yes. If you mean dividing a whole number INTO a fraction here is how you do it. Take the whole number and write it as a fraction where the whole number is the numerator (top part of the fraction) and the number "1" is the denominator (the bottom part of the fraction). Now, turn that fraction upsides down so that the "1" is on top and the whole number is on the bottom. Multiply the numerator of the original fraction times the "1" giving you the original numerator as the new numerator. Multiply the whole number times the original denominator giving you the new denominator. If you means dividing the fraction into the whole number it is similar. Write the whole number as a fraction (as above) with 1 in the denominator. Then flip the fraction over and multiply the two numerators, the two denominators and you have your answer.

Convert it to an improper fraction and multiply.

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.

Invert the fraction and multiply.

Multiply the numerator and denominator by the same whole number.

You multiply the fraction by any non-zero multiple of its denominator.
