Answer:

The closet equivalent of the ratio of 'a' to 'c' is:

$\frac{a}{c}=1.680\:$

Step-by-step explanation:

Given

a is 63% of x

i.e.

a=0.63x

c is 3/8 of x.

i.e.

c=3/8x

Hence,

$\frac{a}{c}=\frac{0.63x}{\frac{3}{8}x}$

$\frac{a}{c}=1.680\:$

Thus, the closet equivalent of the ratio of 'a' to 'c' is:

$\frac{a}{c}=1.680\:$
