I think I may be missing something ... I don't completely understand your question.
All you need to make a fraction is two numbers and a bar. The bar can be either
horizontal or slanty. Then you write one number on top and the other number on
the bottom, and bada-bing, you have a fraction.

You can make fractions like

   2700 / 600
   27 / 6
   9 / 2    (all 3 of these have the same value)

   600 / 2700
   6 / 27
   2 / 9 (all 3 of these have the same value)

Answer:

Mean = 30

standard Deviation = 2.74

Step-by-step explanation:

Formula

mean = np

Standard Deviation = $\sqrt{npq}$

from the question = 40

P = 75% or 0.75

q = 1 - p = 1 - 75% or 1 - 0.75

To find mean

mean = 40 x 0.75

= 30

For Standard Deviation (SD)

Standard Deviation = $\sqrt{npq}$

= $\sqrt{40 X 0.75 X 0.25$

= $\sqrt{7.5}$

:. Standard Deviation = 2.74
