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.

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 times a mixed fraction by a 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).
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
