You multiply across the top and then bottom of the sum, for example: 1/5 x 2/3 = 2/15
These sums can also be simplified before multiplying so the answer is a smaller fraction, for example: unsimplified 2/10 x 3/15 = 6/150, or simplified 2/10 x 3/15 = 1/5 x 1/3 = 1/15, these answers are the same just the second is an easier piece of data to work with and what examiners look for. Simplifying the fractions before multiplication is also easier than doing it afterwards.
Simplifying can be carried out across different fractions during multiplication as long as one is a numerator (on the top) and one is a denominator (on the bottom), for example: 3/10 x 2/9
= 1/10 x 2/3 (where 3 and 9 cancel)
= 1/5 x 1/3 (where 2 and 10 cancel)
= 1/15
Multiplying fractions is no problem top times top bottom times bottom. Dividing fractions is easy as pie, flip the second fraction and multiply. Your welcome!!!!! (: that is one math jingle.
When cross multiplying, finding the product of the means and extremes, you are technically getting a common denominator that reduces out.
When multiplying 2 fractions, we multiply the two numerators together and the two denominators together.
This is related to the fact that dividing by a number is the same as multiplying with the number's reciprocal.
if you have mixed numbers you make them into improper fractions before you multiply
you use multiplication in math because somtimes you need it. like with fractions multiplying and adding are completely different
definition of multiplying fractions?
It depends on the specific problem. If you have an equation that involves fractions, quite often you'll need to multiply them.

it works when comparing fractions by multiplying the fractions to see whitch one is greater not greater and equal
Multiplying fractions is all about division

It is very easy and all you are doing in Elementary is adding and subtracting and multiplying and division and stuff like that. Fractions
Fractions and decimals are usually rational numbers. Besides, multiplying rational and irrational numbers is also similar.
When multiplying 2 fractions, we multiply the two numerators together and the two denominators together.
