How would I solve? Use each of the digits 3,7,1,5 once to write a number that rounds to the number given. 1. 2,000 2. 3,500 3. 6,000 4. 7,320
Is this intended to be a significant figures exercise?
If so then
1753 to 1 sig fig is 2000
3517 to 2 sig figs is 3500
5713 to 1 sig fig is 6000
7315 to 3 sig figs is 7320
1700 3,500 1,600 7,400

Answer this Question
Use the digits 3, 7, 1, & 5 to write a number that rounds to each of the following numbers. 1700, 3500,1600 and 7400
im just kidding
To solve this, we need to find a way to arrange the digits 3, 7, 1, and 5 to create numbers that round to the given numbers. Let's work through each question step by step:
1. For a number to round to 2,000, it must be closer to that number than to any other. In this case, the closest number is 2,000 itself. Therefore, we can arrange the digits in any order, like 5, 3, 7, 1 to create the number 5,371. However, to make it a round number, we can add two zeros to the end, resulting in 5,371 + 00 = 5,371 + 0 = 5,371 = 2,000.
2. For a number to round to 3,500, it needs to be closer to that number than to any other. In this case, the closest number is 3,500 itself. So we can arrange the digits in any order, like 7, 5, 1, 3 to create the number 7,513. Again, to make it a round number, we add two zeros at the end, resulting in 7,513 + 00 = 7,513 + 0 = 7,513 = 3,500.
3. For a number to round to 6,000, it should be closer to that number than to any other. The closest number is 6,000 itself. So we can arrange the digits in any order, like 1, 7, 5, 3 to create the number 1,753. Adding three zeros at the end will give us 1,753 + 000 = 1,753 + 0 = 1,753 = 6,000.
4. For a number to round to 7,320, it must be closer to that number than to any other. Here, the closest number is 7,320 itself. We can arrange the digits in any order, like 7, 1, 5, 3 to create the number 7,153. Since it is already rounded to the nearest hundred, there's no need to add any zeros.
By following the steps above, you can use each of the digits 3, 7, 1, and 5 once to write a number that rounds to the given numbers.
