Final answer:
To round 725,000 to the nearest multiple of 10,000, we round up to 730,000. To round 725,000 to the nearest multiple of 100,000, we round down to 700,000. To write a 4-digit number with 17 hundreds and 52 ones, we get 1752.
Step-by-step explanation:
To round a number to the nearest multiple of 10,000, we need to look at the thousands place. If the thousands place digit is 0 to 4, we round down, and if it is 5 to 9, we round up. In the given number 725,000, the thousands place digit is 5, so we round up to the next multiple of 10,000, which is 730,000.
To round a number to the nearest multiple of 100,000, we need to look at the hundred thousands place. If the hundred thousands place digit is 0 to 4, we round down, and if it is 5 to 9, we round up. In the given number 725,000, the hundred thousands place digit is 2, so we round down to the nearest multiple of 100,000, which is 700,000.
To write a 4-digit number with 17 hundreds and 52 ones, we can multiply 17 by 100 and 52 by 1. The 17 hundreds is equal to 1700, and the 52 ones is equal to 52. Adding these two numbers together, we get the final result of 1752.
