The first thing you do is find the common denominator ...10 divided into 20 is 2 and then 2times 10 is 20...so the common denominator is 20...now you work with the numerators 2 times 8 equal 16 and the problem looks like this 16/20 * 8/20= (16*8)/(20)=128/20 then you divide 20 into 128 and you will get a reminder of 8 the answer is [B]6 8/20 [/B]and reduce or simplify 6 2/5

When you multiply fractions, all you do is multiply the numerators together, and the denominators together, then simplify.

numerator
denominator


So:

8 x 8
10 20

8x8
10x20

64 Then simplify.
200

64/200 Divide both numerator and denominator by 2.
32/100 Repeat.
16/50 Repeat
8/25 Cannot simplify any more, so that's the answer :]


&& you just do the same for the other multiplying fractions.

Pikkulintu...re read ...find the common denominator in the beginning...there is an error...if your are multiplying the number...it should be higher than the problem not closely equal too the problem...

With simple numbers like that you can always just cross multiply and then reduce. so it would be something like 8*20 and then 8*10 and then redues the fraction to lowest terms.

OK you are right been in logic to long...need to revisit basics...

im my own enemy

I agree with pikkulintu. just multiply straight across and simplify
