When multiplying 2 fractions, we multiply the two numerators together and the two denominators together.
Multiplying fractions is the easiest operation you can do with them. Nothing complicated is required, just multiply the top two and the bottom two. Simple as that!
There is no difference in the procedure.
Because you can't add or subtract fractions that have different denominators. Making them like fractions, by multiplying so the denominators are the same, you can add and/or subtract them.
Cross-multiplying is when you have two fractions, and you multiply the numerator of each fraction by the other fractions's denominator. In other words, if you have two fractions a/b and c/d, cross-multiplying would be finding a*d and b*c. If a/b=c/d, then ad = bc.

Multiplying the denominators together of two or more unlike fractions will get you a common multiple.

if you mean multiplying something by a fraction where the numerator is smaller than the denominator then yes.

You add two fractions with a different denominator by multiplying the denominators by a number that will make them equal. Be sure to multiply the numerator by that number too.
Yes, then do the same for the denominators. But THEN you are usually expected to simplify the resulting fraction.
multiplying rational expressions means multiplying two alg. rxpressions that look like fractions, Just like normal, multiply numerators and multiply denominators then reduce. Division, just like regular fractions means to invert the divisor and the multiply (as above)
Make the demoninators (bottom numbers) the same by multiplying the top and bottom of one (or both) fractions, then add them as you would with integers.
