definition of multiplying fractions?

Fractions and decimals are usually rational numbers. Besides, multiplying rational and irrational numbers is also similar.

probably to multiply easier

When multiplying 2 fractions, we multiply the two numerators together and the two denominators together.

The algorithm is A/B * C/D = AB/CD.

it is euclidean algorithm...

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

It is similar because when you divide fractions you are technically multiplying the second number's reciprocal. (Turning the fraction the other way around)

Fractions aren't really difficult, once you understand them. Mainly, you have to memorize when to use which operation, so that you don't get adding and multiplying fractions confused, for example.

No.

When multiplying fractions the algorithm to use is: multiply the numerators and multiply the denominators to create a new fraction. Thus 3/8 * 3/5 = (3*3)/(8*5) = 9/40.

The answer to this question depends on the multiplication algorithm you are working with. If you are working with an algorithm for multiplying fractions, the answer of why it works the way it does is going to be different than if you are multiplying whole numbers. If you are looking to explain multiplication algorithms to young children (and even to explain algorithms to older children or to better understand them yourself), it is useful to use physical objects and play with multiplication. Once you work out a few of the type of problem you are doing (or a scaled down version if you are working with large numbers) it will likely become clearer to you why it works the way it does.

Many of them.
