Worksheet Problems and Solutions

#### Problem 1:
$$
0.8 - 0.4 = \ ?
$$
- Align the decimals:
$$
\begin{array}{r}
0.8 \\
- 0.4 \\
\hline
\end{array}
$$
- Subtract the tenths place: \( 8 - 4 = 4 \).
- The result is:
$$
0.8 - 0.4 = 0.4
$$

#### Problem 2:
$$
3.7 - 1.9 = \ ?
$$
- Align the decimals:
$$
\begin{array}{r}
3.7 \\
- 1.9 \\
\hline
\end{array}
$$
- Subtract the tenths place: \( 7 - 9 \). Since 7 is less than 9, borrow 1 from the ones place (3 becomes 2, and 7 becomes 17):
$$
17 - 9 = 8
$$
- Subtract the ones place: \( 2 - 1 = 1 \).
- The result is:
$$
3.7 - 1.9 = 1.8
$$

#### Problem 3:
$$
5.2 - 4.6 = \ ?
$$
- Align the decimals:
$$
\begin{array}{r}
5.2 \\
- 4.6 \\
\hline
\end{array}
$$
- Subtract the tenths place: \( 2 - 6 \). Since 2 is less than 6, borrow 1 from the ones place (5 becomes 4, and 2 becomes 12):
$$
12 - 6 = 6
$$
- Subtract the ones place: \( 4 - 4 = 0 \).
- The result is:
$$
5.2 - 4.6 = 0.6
$$

#### Problem 4:
$$
9.7 - 6.5 = \ ?
$$
- Align the decimals:
$$
\begin{array}{r}
9.7 \\
- 6.5 \\
\hline
\end{array}
$$
- Subtract the tenths place: \( 7 - 5 = 2 \).
- Subtract the ones place: \( 9 - 6 = 3 \).
- The result is:
$$
9.7 - 6.5 = 3.2
$$

#### Problem 5:
$$
7.9 - 7.9 = \ ?
$$
- Align the decimals:
$$
\begin{array}{r}
7.9 \\
- 7.9 \\
\hline
\end{array}
$$
- Subtract the tenths place: \( 9 - 9 = 0 \).
- Subtract the ones place: \( 7 - 7 = 0 \).
- The result is:
$$
7.9 - 7.9 = 0.0
$$

#### Problem 6:
$$
8.4 - 6.8 = \ ?
$$
- Align the decimals:
$$
\begin{array}{r}
8.4 \\
- 6.8 \\
\hline
\end{array}
$$
- Subtract the tenths place: \( 4 - 8 \). Since 4 is less than 8, borrow 1 from the ones place (8 becomes 7, and 4 becomes 14):
$$
14 - 8 = 6
$$
- Subtract the ones place: \( 7 - 6 = 1 \).
- The result is:
$$
8.4 - 6.8 = 1.6
$$

#### Problem 7:
$$
7.5 - 1.3 = \ ?
$$
- Align the decimals:
$$
\begin{array}{r}
7.5 \\
- 1.3 \\
\hline
\end{array}
$$
- Subtract the tenths place: \( 5 - 3 = 2 \).
- Subtract the ones place: \( 7 - 1 = 6 \).
- The result is:
$$
7.5 - 1.3 = 6.2
$$

#### Problem 8:
$$
40.4 - 3.2 = \ ?
$$
- Align the decimals:
$$
\begin{array}{r}
40.4 \\
- 3.2 \\
\hline
\end{array}
$$
- Subtract the tenths place: \( 4 - 2 = 2 \).
- Subtract the ones place: \( 0 - 3 \). Since 0 is less than 3, borrow 1 from the tens place (40 becomes 39, and 0 becomes 10):
$$
10 - 3 = 7
$$
- Subtract the tens place: \( 3 - 0 = 3 \).
- The result is:
$$
40.4 - 3.2 = 37.2
$$

100.6 \\
- 4.4 \\
\hline
\end{array}
$$
- Subtract the tenths place: \( 6 - 4 = 2 \).
- Subtract the ones place: \( 0 - 4 \). Since 0 is less than 4, borrow 1 from the tens place (100 becomes 99, and 0 becomes 10):
$$
10 - 4 = 6
$$
- Subtract the tens place: \( 9 - 0 = 9 \).
- Subtract the hundreds place: \( 1 - 0 = 1 \).
