Question

add. 8.5 + 5.16

Explanation:

Step1: Align decimal points

Write the numbers as \( 8.50 + 5.16 \) (adding a zero to 8.5 to have the same number of decimal places).

Step2: Add the numbers

Add the hundredths place: \( 0 + 6 = 6 \).
Add the tenths place: \( 5 + 1 = 6 \).
Add the ones place: \( 8 + 5 = 13 \), carry over 1 to the tens place.
The tens place has 1 (from the carry), so the result is \( 13.66 \).

Answer:

\( 13.66 \)
