Answer 2

125.771

Explanation:

When adding or subtracting decimals, you need to line up the decimals and place values like in the image. The other thing you need to do is fill in the missing decimal places with zeros. Since you have 3 decimal places in 2.851, the other numbers need 3 decimal places. Then you can add.

2.851

19.500

103.420
