I see that you've uploaded a photo containing several math problems. Let me go through them step by step:

1. 6.5 − 5

   • This is a simple subtraction.
   • $6.5 - 5 = 1.5$

2. 3.8 × 3

   • This is a multiplication problem.
   • $3.8 \times 3 = 11.4$

3. 2.6 − 1.8

   • This is a subtraction.
   • $2.6 - 1.8 = 0.8$

4. 5.4 ÷ 1.1

   • This is a division problem.
   • $5.4 \div 1.1 \approx 4.91$

The expression on the right side is asking to Evaluate 97.1 × 327. Let's calculate that as well:

5. 97.1 × 327
   • This is a multiplication problem.
