Answer:
3.5
Step-by-step explanation:
we can divide that
- the square root of 5
- less than
- twice a number is 7
as you see the first one is really easy

the second one is < because it points to the lower number
the third one we have
twice a number is 7
let's say x is the number
so twice x is 7
twice means 2 times
so 2 times x is 7

so the number is 3.5

A
rational number is any number that can be written as the
ratio between two other numbers i.e. in the form

Part A:
An easy choice that makes sense is 7.8, right in the middle. To prove that it's rational we need to write it as a ratio. In this case we have

Part B:
We need a number that can't be written as a ratio (because it neither terminates nor repeats). Some common ones are

,

,

and

so it makes sense to try and use those to build our number. In this case

works nicely.
9/50 is close to 10/50 or 1/5 or 0.2
7/15 is close to 7/14 or 1/2 or 0.5
0.2 + 0.5 = 0.7
0.7 is closer to 0.5 than 1
The answer would be B
