Step-by-step explanation:

(1)

Half of 100 is 50. So, the smallest number that rounds to 500 is 500 - 50 = 450.

(or) 

Given the number is 500. As u can see the ten's digit is 0.

There is a rule:

If the digit is 0,1,2,3,4. Then the hundreds digit does not change and we have to round to the previous hundred.

500 ~ 450.

Therefore the smallest number which when rounded to 500 is 450.

(2)

The greatest number that round 500 to the nearest 100 would be 500 + 50 - 1 = 549. It won't be 550 because of 550 rounds to 600. 

Hope this helps
