Answer this Question
To write a number using the digits 3, 7, 1, and 5 that rounds to 2000, you can follow these steps:
Step 1: Start with the thousands place by selecting a number that ends with the digit 1 or 5, which will allow us to round to 2000. The only option available is 2001.
Step 2: Fill in the hundreds place. We have the options of using either 3 or 7. To round the number to the nearest thousand, we need to ensure that the number in the hundreds place is less than 5. Therefore, we choose 3.
Step 3: Fill in the tens place. For the tens place, we can use the remaining digits 7 or 5. Whichever digit we choose will not contribute to rounding the number since the number in the hundreds place is less than 5. Let's use 7.
Step 4: Finally, fill in the ones place. The only digit left is 5, so we will use that.
By following these steps, the number we can write using the digits 3, 7, 1, and 5 that rounds to 2000 is 2001.
To write a number using the digits 3, 7, 1, and 5 once that rounds to 2000, you need to determine the place value of each digit.
First, let's look at the thousands place, which is the leftmost digit in a four-digit number like 2000. In order for the number to round to 2000, the digit in the thousands place must be either 2, 3, 4, 5, 6, 7, 8, or 9. However, since we only have the digits 3, 7, 1, and 5, we cannot use any of them in the thousands place. So, we are left with only the option of putting the digit 2 in the thousands place.
Next, let's consider the hundreds place. Since the number needs to round to 2000, the digit in the hundreds place must be less than 5 to round down. Looking at the remaining digits 3, 7, 1, and 5, we have two options: 3 or 1. We will choose the smaller digit, which is 1, to place in the hundreds place.
Moving on to the tens and ones places, we have two remaining digits: 3 and 7. We can place either of these digits in either the tens or ones place, as they don't affect the rounding. Let's place the digit 3 in the tens place and 7 in the ones place.
Putting it all together, the number that rounds to 2000 using the digits 3, 7, 1, and 5 once is 2137.
