Compare Decimals: Determining the Relationship Between 0.12 and 0.3

Question

Determine the appropriate sign (?) according to the number line:

$0.12?0.3$

00:00 Set the appropriate sign

00:03 We'll use the number line to find the 2 numbers

00:06 If the number is to the left of the second number then it's smaller, and to the right it's larger:

00:09 We'll identify the position of our number in relation to the second number

00:12 And this is the solution to the question

Let's first look at the number 0.3.

We will add a 0 on the end so we can better compare it to 0.12:

$0.3=0.30$

Now, if we look at the numbers after the decimal point, we can observe that:

$0.12<0.30$
