**Answer:**

100

**Step by Step Explanation:**

**H****T****O** - 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.

**H****T****O**0 0 0 - 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. Replacing 0 with one at the ones place, we have:

This is a 1-digit number.**H****T****O**0 0 1 Replacing 0 with one at the tens place, we have:

This is a 2-digit number.**H****T****O**0 1 0 Replacing 0 with 1 at the hundreds place, we have:

This is a 3-digit number.**H****T****O**1 0 0 - So, we see that the smallest 3-digit number is
