Line up the decimal points and add from right to left, keeping each place value in its column. For 27.34 and 12.95, the hundredths are 4 and 5, giving 9. The tenths are 3 and 9, giving 12, so write 2 and carry 1. The ones are 7 and 2, plus the carried 1 makes 10, so write 0 and carry 1. The tens are 2 and 1, plus the carried 1 makes 4. This gives 40.29.
