Nope sorry, it needs a numerical answer :(

Answer 4

thats cool , i'll keep working on it!! :)

Answer 5

Okay, sorry I couldn't'tr be more of a help :(

Answer 6

thats okay

Answer 7

Okay, I'll give you a couple tips. 30 is 15% of the kids. If you times both numbers by 5, you get:
150 people = 75%.
Now, if you can't multiply your beginning numbers any higher than that. For instance, if you multiply 30 and 15 by 6, you get:
180 people = 90%.
Now that's too high! But, you can multiply your numbers by something in between 5 and 6 to get it closer to the percent you need to be at (85%).

Do you get where I'm coming from?

Answer 8

sorta yeah

Answer 9

All you have to do is multiply it by a decimal number beginning with 5. Like, 5.1, and 5.2, and so on until you get to your approximate percentage.

Answer 10

Ok .... so thats all i need to do is find the percentage?

Answer 11

Indeed! If I'm correct, that's all you need to do. Once you get close enough to the percentage of where you need to be, multiply the number you got with thirty. If you need any further help, contact me. I got your back, bro. :P
