10m/11p.44p/20k.15k/8m
we are multiplying and dividing rational expressions. can ne1 help?
I have no idea what you need. Your first line makes no sense.
i know, it doesn't make any sense to me either...it's fractions 10m/11p times 44p/20k times 15k/8m. we have to multiply and simplify
10m/11p*44p/20k*15k/8m
remember that denominators can divide into numerators..
look at the llp and the 44p. that reduces to 4 in the numerator.
10m*4/20k*15k/8m
The 15k/20k reduces to 4/5
10m*4 *5/8m
Now the 10m/8m reduces to 5/4
5/4*4 *5
the 4/4 reduces to 1, so..
5*5
25 is the answer.
ok, but what happened to the letters? don't they remain part of the problem? also, how does 15k/20k reduce to 4/5? thanks for your help. joshua
