What is the smallest 3-digit number?

Answer:

100

Step by Step Explanation:

We have to find a 3-digit number, so we will fill the digits in the place value chart given below.

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:

H T O

0 0 1
This is a 1-digit number.

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

H T O

0 1 0
This is a 2-digit number.

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

H T O

1 0 0
This is a 3-digit number.
So, we see that the smallest 3-digit number is 100.
