Place Value Calculation: Converting 8 Hundreds, 2 Tens, and 5 Ones

To solve this problem, let's assign the given values to their respective decimal place values and construct the number:

• Step 1: Assign the values to their decimal places:
  - Hundreds: We have 8 -> This means 8 in the hundreds place -> $8 \times 100 = 800$.
  - Tens: We have 2 -> This means 2 in the tens place -> $2 \times 10 = 20$.
  - Ones: We have 5 -> This is simply 5 -> $5$.
  
• Step 2: Sum these values to form the number:
  - Total: $800 + 20 + 5 = 825$.

Thus, the number composed using the given place values is $825$.
