What is the sum of 0.3 and 0.8?

Explanation:
Adding decimals is easiest when you think in tenths and line up the decimal points. 0.3 is 3 tenths and 0.8 is 8 tenths, so together they’re 11 tenths. That makes 1 whole and 1 tenth, i.e., 1.1. Rewriting with two decimals confirms this: 0.30 + 0.80 = 1.10, which is the same as 1.1. So the correct value is 1.1.
