how do you multiple fractions such as 3/8x2/3, 4 2/3x 3 7/8, and 1/3x4/8?

just go straight across.
like: 3/8 x 2/3 = 6/24 which simplifies to 1/4
Because on the top: 3x2=6 and on the bottom: 8x3=24
Then 6 goes into itself once and into 24 four times: 1/4

You would multiply the numerator (top number) of the first fraction by the denominator (bottom number), that is, multiply across.
Example: 3/8 * 2/3 = (3*2)/(8*3) = 6/24 = 1/4
To multiply the second number, do the same thing after turning each number into an improper fraction.
Example: 4 2/3 * 3 7/8 = 14/3 * 31/8 = (14*31)/(3*8) = 434/24 = 217/12 = 18 1/12

cross multiplication; example 1/4 x 1/2 multiply 1x2= 2 and 4 x 1=4 , therefore 2/4=1/2 its easier in this form
1 1
---x ---- =
4 2

3/8 x 2/3 = 1/4
you have to cross cancel... 2 goes into 8 four times so you cross out the 8 and make it a 4... 2 goes into 2 one time so cross out the 2 and make it a one... then 3 goes into three one time. so cross out both threes and make them ones... then multiply straight across and you are left with 1/4

Yeah, like the other answers say, it's simple. In multiplication you don't have to find common denominators or anything. Just multiply the numerators, then multiply the denominators.

you do the top multiplied by the top and you put that over the bottom multiplied by the bottom
