Question

solve.
36.24 - 0.4

Explanation:

Step1: Align decimal points

Write the numbers vertically with decimal points aligned:

$$\begin{align*} 36.24\\ - \ \ 0.40\\ \hline \end{align*}$$

(We add a zero to 0.4 to make it 0.40 for easier subtraction in the hundredths place.)

Step2: Subtract column by column

• Subtract the hundredths place: \(4 - 0 = 4\)
• Subtract the tenths place: \(2 - 4\) is not possible, so we borrow 1 from the ones place. The 6 in the ones place becomes 5, and the 2 in the tenths place becomes 12. Then \(12 - 4 = 8\)
• Subtract the ones place: \(5 - 0 = 5\)
• The tens place remains 3.

Putting it all together:

$$\begin{align*} 36.24\\ - \ \ 0.40\\ \hline 35.84\\ \end{align*}$$

Answer:

\(35.84\)
