More than that.
You need to multiply the whole number, the farctions AND cross multiply the whole numbers and the fractions. Then add together all the answers.
23/4 * 56/7 = 2*5 + (3/4*6/7) + 2*6/7 + 3/4*5
Actually, it is far simpler to convert the mixed fractions to improper (top heavy) fractions, and then multiply the numerators together to give the numerator of the answer and multiply the denominators together to give the denominators of the answer.
if you have mixed numbers you make them into improper fractions before you multiply
you have to turn them into improper fractions before you multiply them.
First change the mixed numbers into improper fractions by multiplying the denominator and the whole number and add the product to the numerator in the mixed numbers and then multiply the numerators and the denominators and divide the numerator by the denominator of the product.
First you change them into improper fractions. Then you multiply the numerator and the denamanator straight across. ;)
Change each mixed fraction to an improper fraction. Do this by multiplying the denominator by the whole number next to the fraction and then adding the numerator to the product you get. Once you do this, multiply fractions normally.
Change the mixed numbers into improper fractions. Multiply and then change back to a mixed number in reduced form as necessary.
It's much easier to multiply fractions than it is to multiply mixed numbers. Try either one some time.
It helps with adding and multiplying fractions sometimes. Its simpler to multiply 3/7 x 9/7 than 1 2/7 x 3/7.
Simplicity of calculation
Convert them to improper fractions and proceed the same way you would multiply two fractions.
You turn the mixed number into an improper fraction then multiply by the reciprocal.
Convert the mixed number to an improper fraction and proceed normally.
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?
Convert them to improper fractions and proceed. The answer will be positive.
You would turn the mixed number into a fraction by multiplying the whole number(the one in the mixed fraction) by the denominator and then you add the numerator to the product. You would then put that number you get and out it over the denominator. For the other whole number, you would put it over one and multiply the two fractions!
No. The commutative and associative laws are valid for any real numbers.
Mixed numbers cannot be turned into proper fractions, but they can be made into improper fractions by multiplying the integer (# on the side) by the denominator (bottom), and then adding that number to the numerator (top).
Convert them to improper fractions, invert the second one and proceed to multiply.
To find the sum of two mixed numbers, turn the mixed numbers into improper fractions (multiply the base with the denominator and add the numerator), then add the two fractions. To add the two fractions, find the LCD (lowest common denominator) and add the two numerators, but leave the denominators the same.
If doing it without a calculator, then convert each mixed fraction into a top-heavy equivalent fraction and then multiply as for fractions.
First convert the mixed numbers into "top heavy (or "improper) fractions". Now multiply each of the improper fractions by each other - this makes the denominators the same. Now you can add both the fractions together (and cancel down if necessary).
Mixed fractions can't become whole numbers.
What you are to do is the mixed numeral is converted to a improper fraction. To do this just simply multiply the denominator with the whole number then add that with the numerator. With that number you end up with will be the numerator over whatever the denominator was. Then you can multiply the fractions.(I'm not a good explainer but i hoped i helped a bit)
you would convert the mixed numbers into fractions where the top number is greater than the bottom number, then multiply both the numerator and the denominator by a number that makes the denominators the same.
To convert a mixed number to an improper fraction, multiply the denominator by the whole number, add that total to the numerator and put the whole thing over the original denominator. 3 and 1/7 = 22/7
