Question

hartnn · Answer

means you need to find the mid-point between 4 an 4.5

just take the average!

$\Large \dfrac{4+4.5}{2} =... ?$

I didn't get any of the choices when I did that :/ have any more ideas to help me?

hartnn · Answer

strange choices,
do you have any other similar solved example ?

anonymous · Answer

no, I don't have any that look like this

hartnn · Answer

ok, i think they need any number between 4 and 4.5
so we'll take each option one by one

hartnn · Answer

sqrt 13
where on number line you think this will lie ?

anonymous · Answer

if it helps this question is about real numbers and comparing them

hartnn · Answer

let me give you an example 

sqrt 28
since 5^2 is 25 
sqrt 25 = 5

and sqrt 28 is just lil bit greater than sqrt 25
so, sqrt 28 will lie between 5 and 5.5
did you get this ?
