You should do your own homework, that's how you learn. You can't always rely on someone else to give you the answers.

1. 1/4*1/2 = 1/8 (multiply the numerators and the denominators)
2. 3/4*8/9 = 1/1*2/3 = 2/3 (3 goes in 9 3 times and 4 goes in 8 2 times, hence the result)
3. 15*2/3 = 5*2 = 10 (3 goes in 15 5 times)
4. convert the mixed fractions as follows
2 1/3 = 7/3 and 3 1/2 = 7/2
so 2 1/3* 3 1/2 = 7/3*7/2 = 49/6 = 8 1/6
5. as described above 4 2/5*3 = 22/5*3 = 66/5 = 13 1/5
6. 5 5/6*2 4/5 = 35/6*14/5 = 7/3*7/1 = 49/3 = 16 1/3
Hope it helps

1/4*1/2 =1/8
3/4*8/9=2/3
15*2/3=10
2 1/3* 3 1/2=49/6=8 1/6
4 2/5*3=66/5=13 1/5
5 5/6*2 4/5=49/3=16 1/3
That had to be homework. Don't ask homework questions on Yahoo or anywhere else on the internet. It is cheating.

I kind of agree with the answer to figure it out for yourself. How about a question that would let you understand how to do this on a test, for example.
Multiplying fractions is just like multiplying and dividing rolled into one nasty package. And throw in addition...
1. For simple fractions, multiply the numerators (top) together and then multiply the denominators (bottom) together. Reduce by dividing out any common factors in the numerator and denominator.
so a/b * x/y = (a*x)/(b*y)
eg. 1/2 * 8/10 = 8/20 = 4/10 = 2/5
2. For compound fractions, convert to simple and then do step 1.
You can do this by multiplying the whole part times the denominator and then adding to the numerator. The other way is similar... try it. The remainder in your long division is the fractional part.
eg 2 5/6 = 2 * 6/6 + 5/6 = 12/6 + 5/6 = 17/6

1/4*1/2 = 1/8
3/4*8/9 = 24/36 or 4/6
15*2/3 = 30/3 or 10
2 1/3* 3 1/2 = 2*3+1/3 * 3*2+1 / 2 = 49/6
4 2/5*3 = 22/5 * 3 = 66/5
5 5/6*2 4/5?
