Question

Please help, will be marked brainliest and given points if correct and explained good!

Answer 1

Hm ok, so the answer here would be 9/40

Kinda big right? Heres my reasoning:

To find the answer when the denominators and different, you cross multiply using each of the bottom numbers like this:

$\frac{5}{5} \frac{*}{*} \frac{5}{8}=\frac{25}{40} \\\\\frac{8}{8} \frac{*}{*} \frac{2}{5} =\frac{16}{40}$

Then we subtract 16 from 25 to get 9.

I would like to simplify, but 40 and 9 don't have any common denominators unfortunately.

Now if you have anymore questions, Please make sure to Like, Comment, and Rate this answer! Also, make sure to send me a Friend request. I'm always up for a Challenge!

Thanks!

ps. could you please mark me Brainlyest? I kinda need it to maintain and reach my next rank... thx
