Let's solve each subtraction problem step by step. 1. **Problem 3: \( 7.2 - 0.5 \)** To perform the subtraction, we can align the numbers by their decimal points: \[ \begin{array}{r} 7.2 \\ -0.5 \\ \hline \end{array} \] Now, we can subtract: - Subtract the tenths: \( 2 - 5 \) requires borrowing. So, we borrow 1 from the 7 (making it 6), and the 2 becomes 12. - Now, \( 12 - 5 = 7 \). - For the whole number part: \( 6 - 0 = 6 \). Therefore, \[ 7.2 - 0.5 = 6.7 \] 2. **Problem 5: \( 6.35 - 1.96 \)** Align the numbers: \[ \begin{array}{r} 6.35 \\ -1.96 \\ \hline \end{array} \] Now, we can subtract: - Start with the hundredths: \( 5 - 6 \) requires borrowing. So, we borrow 1 from the tenths (making it 2), and the 5 becomes 15. - Now, \( 15 - 6 = 9 \). - Next, the tenths: \( 2 - 9 \) requires borrowing again. We borrow 1 from the 6 (making it 5), and the 2 becomes 12. - Now, \( 12 - 9 = 3 \). - Finally, the whole number part: \( 5 - 1 = 4 \). Therefore, \[ 6.35 - 1.96 = 4.39 \] 3. **Problem 4: \( 9.5 - 3.7 \)** Align the numbers: \[ \begin{array}{r} 9.5 \\ -3.7 \\ \hline \end{array} \] Now, we can subtract: - Start with the tenths: \( 5 - 7 \) requires borrowing. So, we borrow 1 from the 9 (making it 8), and the 5 becomes 15. - Now, \( 15 - 7 = 8 \). - For the whole number part: \( 8 - 3 = 5 \). Therefore, \[ 9.5 - 3.7 = 5.8 \] ### Summary of Results: - \( 7.2 - 0.5 = 6.7 \) - \( 6.35 - 1.96 = 4.39 \) - \( 9.5 - 3.7 = 5.8 \)
