You are repairing your computer and need to loosen a screw that is fastening the top case down. You tried a 3/4 mm screwdriver, which was too large, and a 5/8 mm screwdriver, which was too small. Which of the following screwdrivers might fit the screw?

Answer:

Since the screw is smaller than 3/4 mm and larger than 5/8 mm,

we can make an inequality from the given data

3/4 > x > 2.5/4

where x is the width of the screw

So since the value is greater than 2.5/4 and less than 3/4,

the approximate value will be the mean of the two values

(2.5/4) + (3/4) = 5.5/4 = 11/8 mm
