Rounding numbers up or down is a way of approximating them to make them more manageable.When you round to the third decimal place, you’re rounding to the nearest thousandth.

- Round this number to 3 decimal places.
- Count along the first 3 numbers to the right of the decimal point.
- Count along the first 3 numbers to the right of the decimal point.
- Count along the first 3 numbers to the right of the decimal point.
- Look at the next number (the 4th number after the decimal place)
What does round to 2 decimal places mean?
What Does it Mean to Round to Two Decimal Places? To round to two decimal places means to find the approximate value of a number up to the hundredths place, which is second to the right of the decimal point.
What is 2.738 to 2 decimal places?
To do that, you must look at the 8 , and see if it is larger then 5, or less than 5. Since it is larger than, you can round the 38 up to 40 . So now the number you have is 2.740 , but since the 0 does not need to be included, you have 2.74 , which is 2 decimal places.
What is the third decimal place?
The third decimal digit from the decimal point is the thousandths digit. For example, 0.008 is eight thousandths.
How many is 4 decimal places?
To have four decimal places is to have four (or fewer) digits to the right of the decimal point when written in decimal notation e.g. 12.3456. Typically we would pad a number with fewer than four digits, so 1.23 would be written 1.2300 in scientific work to indicate its precision level.
What does 3 significant figures look like?
We round a number to three significant figures in the same way that we would round to three decimal places. We count from the first non-zero digit for three digits. We then round the last digit.For example, 20,499 to three signifcant figures is 20,500.
How do you round off decimal places?
There are certain rules to follow when rounding a decimal number. Put simply, if the last digit is less than 5, round the previous digit down. However, if it’s 5 or more than you should round the previous digit up. So, if the number you are about to round is followed by 5, 6, 7, 8, 9 round the number up.
What is the number 2.0847 to 2 decimal places?
Answer is “2.08“
What does two decimal places look like?
If we want to round 4.732 to 2 decimal places, it will either round to 4.73 or 4.74.4.737 rounded to 2 decimal places would be 4.74 (because it would be closer to 4.74). 4.735 is halfway between 4.73 and 4.74, so it is rounded up: 4.735 rounded to 2 decimal places is 4.74.
What is the fifth decimal place called?
thousandths place
a) The 5 is three decimal places to the right of the decimal point. The number 1 followed by three zeroes is 1,000, so: the 5 is in the thousandths place.

What does it mean to round to the nearest decimal place?
Rounding is a process to estimate a particular number in a context. To round a number look at the next digit in the right place, if the digit is less than 5, round down and if the digit is 5 or more than 5, round up.
What does the decimal place mean?
Definition of decimal place
: the position of a digit as counted to the right of the decimal point in a decimal.
What does 0 decimal places mean?
Accuracy and Scientific Notation
The decimal point is a period written between the digits of a number. If there is no decimal point, it is understood to be after the last digit on the right and there is no place (zero place) accuracy.
How do you round to 7 decimal places?
If the next smallest place value is greater than or equal to five (5, 6, 7, 8, or 9), you increase the value of the digit you’re rounding to by one (+1). Just like before, any remaining digits before the decimal point become zeros, and any that are after the decimal point are dropped. This is called rounding up.
What is round off in math?
What is Rounding Off? Rounding off means a number is made simpler by keeping its value intact but closer to the next number. It is done for whole numbers, and for decimals at various places of hundreds, tens, tenths, etc. Rounding off numbers is done to preserve the significant figures.
What does rounding to significant figures mean?
When you are rounding a number to 1 significant figures, you are trying to reduce the number to a single digit and zeros (and possibly a decimal point) to indicate its place value.
How many decimal places is 3 significant figures?
Rounding to significant figures

|---|---|---|
| 6 | 0.0123450 | 0.012345 |
| 5 | 0.012345 | 0.01234 or 0.01235 |

What is the rule for rounding off numbers?
Here’s the general rule for rounding: If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up. Example: 38 rounded to the nearest ten is 40. If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down.
What is roundoff example?
In rounding off numbers, the last figure kept should be increased by 1 if the first figure dropped is greater than 5. For example, if only two decimals are to be kept, then 6.4872 becomes 6.49. Similarly, 6.997 becomes 7.00.
