A 3-digit number cannot have a decimal place.
1. you take the 3 decimal place and if it is 0.005 or higher the decimal in the 2nd place goes one up but if lower it stays the same

A decimal number is simply a way of representing a number in such a way that the place value of a one is ten times that of a one in the place to its right. If it does not contain a fractional part then the decimal representation does not require a decimal point. So the decimal for -3 is -3 : exactly as in the question.

A 3-digit number cannot have a decimal place.
3 is in hundredths place.
To write 7 and 3 tenths as a decimal, you simply place the digit "3" in the tenths place after the decimal point. Therefore, 7 and 3 tenths written as a decimal is 7.3.
Right most 5 (after the decimal) has a place value of 5/100 3 (after the decimal) has a place value of 3/10 Left most 5 (before the decimal) has a value of 5

It is 49.3 to 1 decimal place because .25 is rounded up to .3
0.05 equivalent to 3-place decimal = 0.050
When rounding 0.3 to one decimal place, you look at the digit immediately to the right of the decimal point, which is 3. Since 3 is less than 5, you do not round up. Therefore, 0.3 rounded to one decimal place remains as 0.3.
