Answer:

100

Step by Step Explanation:
  1. We have to find a 3-digit number, so we will fill the digits in the place value chart given below.
    HTO
  2. As we have to find the smallest 3-digit number, we will choose the smallest digit from the digits from the digits 0 to 9.
    The smallest digit is 0.
    Let us fill 0 at all the places in the place value chart.
    HTO
    000
  3. We see that the value of 000 is 0, which is not a three digit number.
    So, we will use the next smallest digit after 0 i.e. 1.

  4. Replacing 0 with one at the ones place, we have:

    HTO
    001
    This is a 1-digit number.

    Replacing 0 with one at the tens place, we have:

    HTO
    010
    This is a 2-digit number.

    Replacing 0 with 1 at the hundreds place, we have:

    HTO
    100
    This is a 3-digit number.

  5. So, we see that the smallest 3-digit number is 100.
