Answer this Question
To create a number using the digits 3, 7, 1, and 5 that rounds to a given number, follow these steps:
1. Identify the given number that you want to round to using the digits 3, 7, 1, and 5.
2. Determine whether the given number rounds up or down based on the digit in the next decimal place.
3. Arrange the digits 3, 7, 1, and 5 to form a number that is close to the given number.
4. Consider the digit in the next decimal place to determine whether to increase or decrease the last digit of the number you formed.
Let's walk through an example:
Given number to round to: 47
Step 1: Identify the given number to round to, which is 47.
Step 2: Since the next digit in the decimal place is 0, 47 rounds down.
Step 3: Arrange the digits 3, 7, 1, and 5 to form a number close to 47. Let's try 37.
Step 4: Since 37 rounds down, we need to increase the last digit, which is 7, to round to 47. The next available digit is 5, so we can change 7 to 5.
Therefore, the number that rounds to 47 using the digits 3, 7, 1, and 5 is 35.
