Question

Answer 1

"A number divided by 2"      well, that's       x/2             [let x be the number]

 

"is no more than"     means    "less than or equal to"     [that is, not "greater than"]

 

5          uh ...   5

 

 

So,

       (x/2) ≤ 5

 

        x ≤ 10              [multiply both sides by 2 and retain the sense of the inequality]

 

Check:

     Try 8 -- it should be True.

          (8/2) ≤ 5       ?

           8 ≤ 10             ? yep, True.

 

     Try 20  ...  it should be False.

          (20/2) ≤ 5       ?

             10 ≤ 5           ? nope. False
