Question

7. Kgomotso, Themba, Jamal and Alison had

dinner at a restaurant. At the end of the
meal, Kgomotso paid of the total bill.
Themba paid 28% of the bill, Jamal
paid 0,3 of the bill and Alison paid of the bill.
8
What percentage of the bill was the tip?

Answer 1

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 499,295÷100 =4,99 which is 4,99%.

I hope this works.
