Question

subtract.
39 - 6.3

Explanation:

Step1: Align the decimal points

Write \( 39 \) as \( 39.0 \) to have the same decimal places as \( 6.3 \). So the subtraction becomes \( 39.0 - 6.3 \).

Step2: Subtract the numbers

Subtract the tenths place: \( 0 - 3 \) is not possible, so we borrow 1 from the ones place. The 9 in the ones place becomes 8, and the 0 in the tenths place becomes 10. Now, \( 10 - 3 = 7 \) (tenths place). Then subtract the ones place: \( 8 - 6 = 2 \) (ones place). The tens place remains 3. So we get \( 32.7 \).

Answer:

\( 32.7 \)
