Question

75.11 - 4.4=

Explanation:

Step1: Align decimal points

Write the numbers vertically with decimal points aligned:

$$\begin{align*} 75.11\\ - \ \ 4.40\\ \hline \end{align*}$$

(We add a zero to 4.4 to make the number of decimal places equal for easier subtraction.)

Step2: Subtract from right to left

• Subtract the hundredths place: \(1 - 0 = 1\)
• Subtract the tenths place: \(1 - 4\) is not possible, so we borrow 1 from the ones place. The 5 in the ones place becomes 4, and the 1 in the tenths place becomes 11. Then \(11 - 4 = 7\)
• Subtract the ones place: \(4 - 4 = 0\) (after borrowing, the 5 became 4, and we subtract 4 from it)
• Subtract the tens place: \(7 - 0 = 7\)

Putting it all together, we get:

$$\begin{align*} 75.11\\ - \ \ 4.40\\ \hline 70.71\\ \end{align*}$$

Answer:

\(70.71\)
