Answer 1

Step-by-step explanation:

1. For estimating to the nearest 10, we look at the digit in the ones place. If it is 0, 1, 2, 3 or 4 we replace it by zero. If the digit in the ones place is 5, 6, 7, 8, or 9 we replace it by zero. If the digit in the ones place is 5, 6, 7, 8 or 9 we replace it by zero and increase the digit in the tens place by 1.
2. When rounding to the nearest hundred, look at the TENS DIGIT of the number. If that digit is 0, 1, 2, 3, or 4, you will round down to the previous hundred. If that digit is 5, 6, 7, 8, or 9, you will round up to the next hundred.
