Please see the attached paper for the inequality and the graph of the possible solutions.
A filled in circle means to include that value.
Answer:
63/70 is simplified to 9/10 in fraction form and 0.9 in decimal form.
14/30 is simplified to 7/15 in fraction form and 0.46 in decimal form.
24/36 is simplified to 2/3 in fraction form and 0.6 in decimal form.
10/50 is simplified to 1/5 in fraction form and 0.2 in decimal form.

18/24 is simplified to 3/4 in fraction form and 0.75 in decimal form.
You can simplify these and future questions by cancelling out the numerator's and denominator's LCF (Least Common Factor). I hope this helps!
You should calculate( the area of a circle of radius 15 cm ) minus the area of the circle of radius (15 cm - width of the frame). I am not able to read the number, sorry.
That is the surface area of the frame.
Then, if area of circle radius is 100%, the % of face of the clock is:
(100xareaCircle(15cm-widthframe))/areaCircle15cm
