B. 48:19

C. 39.6%

Step-by-step explanation:

A. the ratio of A to B is when a=190 and b=480

A:B = A/B

190:480 = 190/480

19:48

B. the ratio of B to A is

B:A = B/A

480:190 = 480/190

48:19

C. A is __percent of B

190 is x% of 480

190 = x% * 480

190/480 * 100 = x

x = 39.6%

A is 39.6% of B
