Find the Decimal Between 0.2 and 0.3: Inequality Problem

Question

What is the missing number number?

$0.2 < ? < 0.3$

00:00 Complete the appropriate number

00:04 We'll use the number line to find the possible numbers

00:23 We can see that all these numbers fit

00:28 Let's choose the appropriate number from the options

00:31 And this is the solution to the question

To find out which numbers appear in our number range, we will first add 0 to both numbers as follows:

$0.2=\text{0}.20$

$0.3=0.30$

This means that our number is between 0.20 and 0.30.

The numbers existing in this range are: $0.21,0.22,0.23,0.24,0.25,0.26,0.27,0.28,$ and $0.29$ .

Looking at the possible answers, we can see that 0.28 must be the correct one.

$0.28$
