What is the value of 3.85 + 0.004 + 0.117?

• A. 3.971
• B. 4.01
• C. 3.9
• D. 4.00

Answer: (A)

To find the value of 3.85 + 0.004 + 0.117, it’s essential to align the numbers correctly by their decimal points to ensure accurate addition. 1. Start with the first number: 3.85, which can also be represented as 3.850 to keep the same number of decimal places. 2. Next, add 0.004; with proper alignment, this becomes 0.0040 when expressed with four decimal places. 3. Finally, take 0.117 and write it as 0.1170 to also maintain four decimal places. Now, organizing the numbers: ``` 3.8500 + 0.0040 + 0.1170 ``` Start adding from the rightmost column: - In the thousandths place, 0 + 0 + 7 = 7. - In the hundredths place, 0 + 4 + 1 = 5. - In the tenths place, 5 + 0 + 1 = 6. - In the units place, 3 + 0 + 0 = 3. Combining these results gives you 3.971. Thus,

+ 0.0040

+ 0.1170

Start adding from the rightmost column:

• In the thousandths place, 0 + 0 + 7 = 7.

• In the hundredths place, 0 + 4 + 1 = 5.

• In the tenths place, 5 + 0 + 1 = 6.

• In the units place, 3 + 0 + 0 = 3.

Combining these results gives you 3.971. Thus,
