The value of a is inversely proportional to b when a = 0.5 and b = 3.25. what is the value of a when b = 2? a.4/13 b.13/16 c.13/8 d.13/4

A=k/b, where k is a non zero constant.
When a=0.5, b=3.25, is
0.5=k/3.25
k=3.25×0.5=1.625
meaning that when there is a value for b, dividing 1.625 by it will form the value of a.
therefore, when b=2, 1.625/2=0.8125, which is 13/16.
answer is 13/16
