Use the digits 3,7,1 and 5 to write a number that rounds to each of the following

1700 3500 1600 7400

1,700

1710

1735, 3517, 1573, 7315

To write a number using the digits 3, 7, 1, and 5 that rounds to each of the given numbers, we need to understand how rounding works.

Rounding means to approximate a number to a specific value based on certain criteria. In this case, we want to round our number to the nearest hundred (rounded to the nearest 100).

Let's go through each of the given numbers and determine how we can use the digits 3, 7, 1, and 5 to write a number that rounds to them.

1. Rounding to 1700:
In the thousands place, we want the digit to be either 1 or 2. To achieve this, we can use the digit 1. For the hundreds place, we want the digit to be 7 or greater. To achieve this, we can use the digit 7. For the tens and ones places, we can use 0.

Therefore, the number that rounds to 1700 using the given digits is 1070.

2. Rounding to 3500:
In the thousands place, we want the digit to be 3 or greater. To achieve this, we can use the digit 3. For the hundreds place, we want the digit to be 5 or greater. To achieve this, we can use the digit 7. For the tens and ones places, we can use 0.

Therefore, the number that rounds to 3500 using the given digits is 3700.

3. Rounding to 1600:
In the thousands place, we want the digit to be either 0 or 1. To achieve this, we can use the digit 1. For the hundreds place, we want the digit to be 6 or less. To achieve this, we can use the digit 1. For the tens and ones places, we can use 0.

Therefore, the number that rounds to 1600 using the given digits is 1100.

4. Rounding to 7400:
In the thousands place, we want the digit to be either 7 or 8. To achieve this, we can use the digit 7. For the hundreds place, we want the digit to be 4 or greater. To achieve this, we can use the digit 7. For the tens and ones places, we can use 0.

Therefore, the number that rounds to 7400 using the given digits is 7700.

So, the numbers that round to 1700, 3500, 1600, and 7400 using the digits 3, 7, 1, and 5 are 1070, 3700, 1100, and 7700 respectively.
