The ratio from USA to India stamps 5:2, The indian to british is 5:1. What is the ratio fro USA to British?

USA to India is 5:2;  Since we have a figure of India to British of 5:1;  we need to determine what the value of "5" Indian is in USA;

5/2 = x/5;  cross-multiply and you get 2x = 25 or x = 12.5

So, 12.5: 5 is also a ratio for USA to India.  Since 5 Indian is the same as 1 British,  we get a USA to British ratio or 12.5 : 1  or  25:2


Hope that helps.
