1. The problem states: "These are 10 tens." We need to find the total value represented by 10 tens. 2. Recall that "ten" means 10 units. So, 1 ten = 10. 3. To find the total value of 10 tens, multiply 10 (the number of tens) by 10 (the value of one ten): $$10 \times 10 = 100$$ 4. Therefore, 10 tens equal 100. Answer: 100
