Determine whether the exercise is written correctly:
Is the position of the decimal point correct in each number?
First let's fill the zeros in the empty space as follows:
Here We should note that the decimal points are written one below the other.
Therefore, the exercise is written in the appropriate form.
Yes
\( \text{0.6+0}.5= \)
Decimal points represent the same place value position in all numbers. When they align vertically, you're adding tenths to tenths, hundredths to hundredths, and so on!
Add zeros to the right of the shorter decimal to make them equal! For example, 6.31 becomes 6.310 so it matches 216.222's three decimal places.
Not for the math, but it's easier to read when the longer number goes on bottom. The most important thing is keeping those decimal points aligned!
Use a ruler or straight edge to check! The decimal points should form a perfectly straight vertical line. Also count that all numbers have the same amount of decimal places.
You'll get the wrong answer! Misaligned decimals mean you're adding wrong place values together, like adding hundreds to ones instead of ones to ones.
