What is the sum of 0.65, 4.2, and 3.85?

To find the sum of 0.65, 4.2, and 3.85, it's important to align the decimal points and add the numbers carefully to ensure accuracy.

First, let's break down the numbers:

• 0.65 can be thought of as 0.65.

• 4.2 can be expressed as 4.20 to align the decimal places.

• 3.85 remains as 3.85.

Now, adding these numbers together:

1. Write them aligned by their decimal points:

0.65

+ 4.20

+ 3.85

______

2. Start by adding the numbers from the rightmost column (the hundredths place):

• 5 (from 0.65) + 0 (from 4.20) + 5 (from 3.85) = 10. Write down 0 and carry over 1 to the next column.

3. Move to the tenths place:

• 6 (from 0.65) + 2 (from 4.20) + 8 (from 3.85) + 1 (carried over) = 17
