can't remember how to round off numbers such as 105,219 to the nearest place value.105,219 is supposed to be rounded off to the nearest hundred thousand. 17,340,206 is supposed to be rounded off to the nearest hundred thousand place value and so on. would appreciate your help. THANKS!
The first number is
one hundred five thousand, two hundred nineteen. Is that closer to one hundred thousand, or two hundred thousand?
The second, seventeen million, three hundred forty thousand, two hundred six.
Is that closer to seventeen million three hundred thousand, or seventeen million four hundred thousand?
You have to look at the digit involved, and sometimes it is easier to read the number to get the right digit.
Find the hundred thousands place. Going from the decimal to the left. The 9 is the units place, the 1 is the tens place, the 2 is the hundreds place, the 5 is the thousands place, the 0 is the ten thousands place and the 1 is the hundred thousands place. So the left most 1 is the number to be rounded. Look at the number to the right of the 1, it is a zero. That is less than 5 so you don't change the 1 and the number becomes 100,000. Some may prefer to write it in exponential form as 1 x 10^5. Check my work.
what is 3 in the 5 place and 3 in the 10 thousonds place and a 8 in the hundreds place
it is between 1 and 2 million.the first three digit are the same.the least possible digit is in the thousands place.the greatest possible digit is in the ones place.the hundreds digit is 1 more than the tens digit.the sum of the digits is 21.
To round off numbers to the nearest place value, you need to determine the place value you want to round to (in this case, the hundred thousand place) and follow these steps:
1. Identify the digit in the place value to the right of the desired rounding place. In this case, it is the ten thousand place, as the hundred thousand place is the desired rounding place.
For the number 105,219:
The digit in the ten thousand place is 2.
For the number 17,340,206:
The digit in the ten thousand place is 0.
2. Determine if the digit in the rounding place (the ten thousand place) is 5 or greater. If it is, you need to round up; if it's less than 5, you round down.
For the number 105,219:
The digit in the ten thousand place is 2, which is less than 5. Therefore, you round down the hundred thousand place to zero.
For the number 17,340,206:
The digit in the ten thousand place is 0, which is less than 5. Therefore, you round down the hundred thousand place to zero.
3. Replace all digits to the right of the rounding place (the hundred thousand place) with zeros.
For the number 105,219:
After rounding down, the number becomes 100,000.
For the number 17,340,206:
After rounding down, the number becomes 17,300,000.
So, rounding off 105,219 to the nearest hundred thousand gives you 100,000, and rounding off 17,340,206 to the nearest hundred thousand gives you 17,300,000.
