To find a number between both decimals, what you can do is take the average of both numbers.
We have then:
[tex] average = \frac{0.4+0.5}{2}
[/tex]
Rewriting we have:
[tex] average = \frac{0.9}{2}
average = 0.45
[/tex]
Therefore, the decimal obtained is a number between 0.4 and 0.5
Answer:
a decimal between 0.4 and 0.5 is:
[tex] average = 0.45 [/tex]
