Answer:
First of all you need to know the [tex]\sqrt {4} [/tex] it's equal to 2 and
[tex]\sqrt {1} [/tex] which is the number is between 1 and 2 and between that number there maybe the possibilities of above 0.5 or under 0.5
After that Figure out which one was bigger? [tex]\sqrt {2}[/tex] or [tex]\sqrt {3}[/tex] ? The answer is [tex]\sqrt {3} [/tex] and [tex]\sqrt {3} [/tex] also near to [tex]\sqrt {4}[/tex] so it should be above 0.5 .
So we know that [tex]\sqrt {2}[/tex] is between 1 and 1.5.
Hopes that information was help you a lot
