What is 0.7 + 0.5?

Explanation:
When adding decimals, line up the decimal points and add digits in the same place value. Here, 0.7 is seven tenths and 0.5 is five tenths. Add the tenths: 7 + 5 = 12 tenths, which is 1 whole and 2 tenths, i.e., 1.2. Another way to see it is to convert to hundredths: 0.7 = 70 hundredths and 0.5 = 50 hundredths, so 70 + 50 = 120 hundredths = 1.20 = 1.2. Since the total is twelve tenths, the result is 1.2.
