Answer:
4440 or 4400
Explanation:
To round 4435 to the nearest 10 we need to look at the number to the right of the 10, if it is a 1-4 we round down, if it is a 5-9 we round up. in this case the 3 is the ten and the 5 is the number to the right. Since it is in the numbers 5-9 we will round up. the nearest 10 above 35 is 40 so the new number will be 4440. We will repeat the process for rounding to the nearest hundred just with the hundred number which is a 4. the number to the right of the hundred is a 3 which means we will round down. the nearest hundred below 435 is 400 so the new number is 4400.
