Round 1,643,253 to the nearest hundred thousand. I say it's 1,600,000 but the workbook says 1,700,000. Please explain.
I agree with your answer. The workbook must be wrong.
Yes, the workbook is wrong.
I double agree, book is wrong
To round a number to the nearest hundred thousand, we need to look at the digit in the hundred thousand place. In this case, the digit in the hundred thousand place is 4.
To determine how to round the number, we look at the digit immediately to the right of the hundred thousand place, which is the ten thousand place in this case.
If the digit in the ten thousand place is less than 5, then we round down (keep the digits in the hundred thousand place and set all the digits to the right of it to zero).
If the digit in the ten thousand place is 5 or greater, then we round up by adding 1 to the digit in the hundred thousand place and setting all the digits to the right of it to zero.
In this case, the digit in the ten thousand place is 3, which is less than 5. Therefore, we round down.
Hence, rounding 1,643,253 to the nearest hundred thousand gives us 1,600,000, as you mentioned.
However, it's also important to note that there are different rounding conventions. In some cases, if the digit in the ten thousand place is 5, it is rounded up. This might explain why the workbook says 1,700,000.
