29.75 and 257.9
It is rounding a decimal representation of a number so that there are two digits after the decimal point.
The answer depends on how many decimal places are in the summands.
You need to add up the number of digits to the right of the decimal to find the number of digits in the answer. If the first factor has 2 digits to the right of the decimal point and the second factor has 3, the final answer will have 5 digits to the right of the decimal point.
To the left of the decimal point, you place a decimal at an interval of every three digits.
Three. This refers to the number of significant digits AFTER the decimal point.

The answer depends on how many decimal places are in the summands.
Pi to 144 decimal places is written thus: 3.14159265358979323846264338327950288419716939937510 58209749445923078164062862089986280348253421170679 82148086513282306647093844609550582231725359 The sum of these first 144 decimal digits (after the decimal point) is 666.
There is no need to round 1097 to any decimal places as there are no digits following a decimal point.
You need to add up the number of digits to the right of the decimal to find the number of digits in the answer. If the first factor has 2 digits to the right of the decimal point and the second factor has 3, the final answer will have 5 digits to the right of the decimal point.
It is a decimal fraction. Not just a decimal, since 2,000,000 for example, is a decimal number.It is a decimal fraction. A decimal number need not have any digits in fractional places.
To the left of the decimal point, you place a decimal at an interval of every three digits.
3.1415926535897932384626433832795 (that's 31 decimal places) !
The number of digits on both sides of the decimal point is up to you! For instance, Pi is accepted as being 3.14 (two places) for general use. But, 3.14159265359 is to 11 places, and it can stretch on into infinity!
Three. This refers to the number of significant digits AFTER the decimal point.
