Question

Math help!
Lets say i have 28 soccer balls.
22 is red and the rest are pink. What is the percentage of red. I just need help trying to see how much "1" is in percentage if the whole is 28.

Answer 1

If you have only pink and red soccer balls, there is something wrong with you.

1 of 10 is 10% 1/10 = 0.10 = 10%
1 of 20 is 5% 1/20 = 0.05 = 5%
1 of 40 is 2.5% 1/40 = 0.025 = 2.5%

Answer 2

just a metaphor ;)

Answer 3

so should I use these as benchmarks?

Answer 4

I still dont understand should i round>

Answer 5

Not really. You should see how to calculate a percentage. It's a division problem.

3 of 10 is 30% 3/10 = 0.30 = 30%
3 of 20 is 15% 3/20 = 0.15 = 15%
3 of 40 is 7.5% 3/40 = 0.075 = 7.5%

Answer 6

If rounding is the rule of the day, then go ahead. If not, then don't.

1/28 is what percent?
3/28 is what percent?
