In an examination Alan obtained 32 out of 40 marks. In another examination Ben obtained ⅝ of the total marks. Express the marks of each candidate as a percentage.

Alan: 80%

Ben: 62.5%

Step-by-step explanation:

5/8 = 0.625 x 100 = 62.5 = 62.5%

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
