If a is 63 percent of x and c is 3/8 of x, then the ratio of a to c is ? (round to 0.001)

Answer 1

I believe that the givens are as follows:

   a = .63 x    

   c = 3/8 x

Thus:

    a/c = (.63 x) / (3/8 x)

         = (.63) (8/3)          (The x’s cancel and to divide by a fraction, you multiply by the inverse.)

    a/c = 1.680 (The zero is necessary because the problem asked to round to this position.)

Answer 2

a=.63x

c=3/8*x-.375x

a/c= (.63x)/(.375x)=1.680

Answer 3

0.63(x+c) =(3/8)x

0.63x+0.63c=(3/8)x

1.68x+1.68c=x

1.68c =0.68x

x/c =2.4706
