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?
Steps for multipling fractions and mixed numbers?
to multiply fractions add them together and reduce the final fraction. to multiply mixed numbers, first make the mixed number an improper fraction, by mulitplying the whole number and the denominator and adding the answer to the numerator. Example: The improper fraction 8/5 can be changed to the mixed number 1 3/5 by dividing the numerator (8) by the denominator (5). This gives a quotient of 1 and a remainder of 3. The remainder is placed over the divisor (5).
Multiplying fractions and mixed numbers?
can't do it as is... you must convert the mixed number to an improper fraction to multiply To convert the mixed number to a fraction you multiply the denominator and the number in front and then add that to the numerator then you put that number over the original denominator ex. 2 1/3 = (3 x 2 + 1)/3 =7/3 then you can multiply: 7/3 X 4/5 = 28/15
