Divide 7/15 by 3/5 you guys are awesome

I did this on another problem on brainy. Same question. Anyways the answer is c. First u divide 7/15 by 3/5 which u would do same change flip and get 7/15 times 5/3 which when u multiply straight across u get 35/45 which then is simplified to 7/9 when divided by five. I hope this helped u!

Well what you can do is press ALPHA->y= and select the fraction. Do this until you get fraction over a fraction. Then, you would plug in the (3/5)/(7/15) and you should get 9/7.

Ithink it is15not sure tho
