Math Problem Statement

Copy and complete the calculation below: 3.143 + 4.39 + 1.68

Solution

The provided image shows a mathematical addition problem involving three numbers:

3.143 \\ 4.39 \\ + 1.68 \\ \hline \end{array}$$ Let's proceed to solve this addition problem step by step: 1. Align the decimal points for the numbers: $$\begin{array}{r} 3.143 \\ 4.390 \\ + 1.680 \\ \hline \end{array}$$ 2. Add the numbers column by column: - Starting from the thousandths place: $$3 + 0 + 0 = 3$$ - Move to the hundredths place: $$4 + 9 + 8 = 21$$ (write 1, carry over 2) - Move to the tenths place: $$1 + 3 + 6 + 2 = 12$$ (write 2, carry over 1) - Finally, the units place: $$3 + 4 + 1 + 1 = 9$$ 3. The final result is: $$\boxed{9.213}$$ Let me know if you would like further clarification, or if you have any additional questions! --- Here are five related questions: 1. How do you add numbers with more decimal places? 2. What is the importance of aligning decimal points in addition? 3. Can subtraction follow the same method as addition for decimals? 4. How do you round a number to two decimal places? 5. How do you add multiple decimal numbers quickly in mental math? **Tip:** Always double-check your decimal point alignment when adding numbers, as a misalignment can lead to incorrect results.
