I'm currently learning about rational equations, and this question has me stumped. So far in your volleyball match, you have made 37 of the 44 serves you have attempted. write a rational equation and solve it to find the number of consecutive serves you will need to make in order to raise your serve percentage to 90%.

OpenStudy (bahrom7893):

What is your current percentage?

OpenStudy (anonymous):

well it doesn't say... however you can get it from the 37 of 44. i got 84%

OpenStudy (anonymous):

So you now have 84% right. Let's say you make another good serve and your ratio goes to 38 to 45

OpenStudy (anonymous):

What's your percentage then?

OpenStudy (anonymous):

yeah i know what you mean. so to get 90% the ratio would have to be 63 to 70?
