Place Value Practice: Converting 6 Ones, 6 Tens, and 6 Hundreds to a Number

To solve the problem of determining the number, we will use the place values provided and construct the number accordingly:

• Step 1: The number of ones is 6, indicating the digit in the units place is $6$.
• Step 2: The number of tens is 6, indicating the digit in the tens place is $6$.
• Step 3: The number of hundreds is 6, indicating the digit in the hundreds place is $6$.

Having established the place values and corresponding digits, the final number is constructed as follows:
- Hundreds place is $6$, so it contributes $600$.
- Tens place is $6$, so it contributes $60$.
- Ones place is $6$, so it contributes $6$.

Therefore, by adding these values, we get the number $666$.

Among the choices provided, the option 666 matches our constructed number.

Therefore, the solution to the problem is $666$.
