Answer:
4,99%
Explanation:
By Themba you write 28/100 because a percentage means 100 ,you 100 by 28 and then your common fraction answer will be 7/25 in a decimal way it is 0,28 .
Jamal is 0,3 which is 0,3 means 3/10 and Alison 1/8 and the answer for Alison is 0,125 or in a common fraction way it is 125/10.
And then you add all the answers and you get 141/200 .
And then 500-7/25-3/10-0,125 and then you get 499,295, and 499,295รท100 =4,99 which is 4,99%.
I hope this works.
