505
——
100
Step-by-step explanation
The 5 at the end is in the hundredths place, so to get a whole number from the hundreds place, you would need 100 hundredths which will = 1. If you have 500 then it would = 5. And since we are representing fractions, we would put 505 —- 100 because we have 5 whole numbers (in this case it requires 100 hundredths to make 1 whole number) and 5 hundredths. Hope this help!
