What is the sum of 12.5 and 1.5?

To find the sum of 12.5 and 1.5, you simply align the numbers by their decimal points and add them together.

Starting with 12.5, you can break it down into its components:

• The whole number part is 12.

• The decimal part is 0.5.

Next, you take the other number, which is 1.5:

• The whole number part is 1.

• The decimal part is 0.5.

Now, add the whole numbers together:

• 12 (from 12.5) + 1 (from 1.5) = 13.

Next, add the decimal parts:

• 0.5 + 0.5 = 1.0.

Finally, combine these results:

• Take the sum of the whole numbers (13) and add the result from the decimal addition (1.0). Thus, 13 + 1.0 = 14.0.

Therefore, the overall sum of 12.5 and 1.5 is 14.0, making the correct option the first choice.
