To find a three-digit number that rounds to the nearest ten and to the nearest hundred, we need to consider the possible rounding scenarios.
When rounding to the nearest ten, the units digit is either rounded up or down based on the tens digit. If the units digit is 5 or greater, it is rounded up; otherwise, it is rounded down.
When rounding to the nearest hundred, the tens and units digits are considered. If the tens digit is 5 or greater, the hundreds digit is rounded up; otherwise, it is rounded down. The tens and units digits become zeros.
With these rules in mind, let's go through the steps to find a suitable number:
Step 1: Consider a three-digit number with the units digit as 5 or greater. For example, let's take 325.
Step 2: Round 325 to the nearest ten: The tens digit is 2, so we round the units digit (5) down. The resulting number is 320.
Step 3: Round 325 to the nearest hundred: The tens digit (2) is less than 5, so we round the hundreds digit (3) down. The resulting number is 300.
Step 4: Since the result after rounding to the nearest ten (320) is the same as rounding to the nearest hundred (300), the number 325 fits the given rule.
Thus, one possible number that fits this rule is 325.
To find a number that fits this rule, we need to understand how rounding works. When rounding to the nearest ten, we look at the digit in the ones place. If the digit is 5 or greater, we round up to the next ten. If the digit is less than 5, we round down to the current ten.
Similarly, when rounding to the nearest hundred, we look at the digit in the tens place. If the digit in the ones place is 5 or greater, we round up to the next hundred. If the digit in the ones place is less than 5, we round down to the current hundred.
Now, let's find a number that satisfies the given rule. We know that when rounded to the nearest ten and hundred, the answer is the same.
Let's consider the number 545. When we round 545 to the nearest ten, the digit in the ones place (5) is 5 or greater, so we round up to the next ten, which gives us 550.
Now, when we round 545 to the nearest hundred, the digit in the tens place (4) is less than 5, so we round down to the current hundred, which gives us 500.
In this case, we can see that rounding 545 to the nearest ten gives us 550, and rounding it to the nearest hundred also gives us 500. Therefore, 545 is one possible number that fits the given rule.
