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.
