I am having trouble rounding numbers for example 67.935 and i have to round it to the tenths, hundreths,and whole
thanks
Look at the next number to the right. If it is more than 5, add 1 to the digit you are rounding. If it is less than 5, keep the digit as is. For example,
67.937 (not the same as your number).
tenths means the 9.
So we look to the right, see a 3, it is less than 5 so we leave the 9 as is and the number rounded to the nearest tenth is 67.9.
hundredths means the 3.
So we look to the right, it is a 7, that is more than 5, so the 3 becomes a 4 and the answer is 67.94.
The nearest whole number is the 7. We look to the right, see a 9, the 9 is greater than 5 so the 7 becomes and 8 and the answer is 68. I didn't give a rule when the number to the right is a 5 (as in your problem) but if that is the case, you round to the EVEN number. That means a 3 becomes a 4 but a 2 stays the same. I can give you a site on the internet if you would like one.
To round a number to the desired decimal place, you need to follow a specific set of rules. Let's go through each case using the number 67.935 as an example:
1. Rounding to the tenths place:
- Look at the digit in the hundredths place (the first digit after the decimal point): 9.
- If the digit in the hundredths place is 5 or greater, you round up the digit in the tenths place.
- If the digit in the hundredths place is 4 or less, you leave the digit in the tenths place as it is.
- In this case, since 9 is greater than 5, you round up the digit in the tenths place, which is 3. The rounded number to the tenths place is 67.9.
2. Rounding to the hundredths place:
- Look at the digit in the thousandths place (the second digit after the decimal point): 5.
- If the digit in the thousandths place is 5 or greater, you round up the digit in the hundredths place.
- If the digit in the thousandths place is 4 or less, you leave the digit in the hundredths place as it is.
- In this case, 5 is equal to 5, so you look at the digit in the hundredths place, which is 3. Since 3 is less than 5, you leave it as it is. The rounded number to the hundredths place is 67.93.
3. Rounding to the whole number:
- Ignore the decimal part of the number and look only at the whole number part.
- If the decimal part is 0.5 or greater, you round up the whole number.
- If the decimal part is less than 0.5, you leave the whole number as it is.
- In this case, the decimal part is 0.935, which is greater than 0.5. Therefore, you round up the whole number, which is 68.
So, rounding the number 67.935 to the tenths place gives 67.9, to the hundredths place gives 67.93, and to the whole number gives 68.
