6. \( 0.51+0.28= \)

Did you know that adding decimals is just like adding whole numbers? You line up the decimal points and then add as usual! So for \( 0.51 + 0.28 \), you start by aligning the numbers: ``` 0.51 + 0.28 ``` Add each column, starting from the right, and you’ll find the answer is \( 0.79 \). Easy peasy! When handling decimals, a common mistake is forgetting to keep the decimal point aligned. This small oversight can lead to incorrect answers, so always double-check your alignment! And if you’re feeling stuck, it can help to visualize the numbers on a number line to see where they land!
