Best Answer

EX:

3 3/4 x 4 4/10

first, you multiply 4x3, then you get 12 + 3=15/4

second, you multiply 10x4=40+4=44/10

then you multiply the denomanator by the denomanator and the numerator by the numerator.

15x44=

10x4=

Then simplify your answer.

Yes, mixed fractions are rational

This number is rational - all fractions, including decimal fractions and mixed numbers are rational.

you have to turn them into improper fractions before you multiply them.

If doing it without a calculator, then convert each mixed fraction into a top-heavy equivalent fraction and then multiply as for fractions.

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 you have mixed numbers you make them into improper fractions before you multiply

Convert them to improper fractions and proceed the same way you would multiply two fractions.

Convert the mixed number to an improper fraction and proceed normally.

Convert them to improper fractions and proceed. The answer will be positive.

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.

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?

A mixed number is a rational number. Mixed numbers are not a rational number but many of them.

Convert them to improper fractions, invert the second one and proceed to multiply.
