Answer 1

Answer: 19.9

===========================================================

Step-by-step explanation:

12.32 rounds to 12.3 when rounding to the nearest tenth (aka one decimal place). The digit in the tenths place stays the same because the next digit over is not 5 or larger.

7.636 rounds to 7.6 when following the same rule

Adding those two rounded values gets us 12.3+7.6 = 19.9
