When you are lining up decimals to add or subtract, always line the decimals up before doing the problem. An example is:
1.468 + 0.0004 would be lined up this way:
1.468
0.0004
1.4684
If this is a bit confusing, you could add a zero to 1.468 and it would be 1.4680.
When doing subtraction, you would do the same. An example is:
4 - 0.086
4 can be written 4.0 or 4.000, so line then up like this:
4.000
-0.086
3.914
Sum is an answer to an addition problem.
0.7 0.5
Two decimals with thousandths whose sum is close to 50 are 24.987 and 25.013.
An infinite number, like 1.25 and 0.75
0.79 4.3
1.502 and 0.499
Sum is an answer to an addition problem.
0.7 0.5
When the fractional parts, if any, of the two decimal numbers sum to 1.
Two decimals with thousandths whose sum is close to 50 are 24.987 and 25.013.
3.14159 and 1.85841 are.
This will happen if the fractional parts of the numbers sum to 1.
For example: 0.25+0.75 = 1.0
An infinite number, like 1.25 and 0.75
0.79 4.3
