A.the fraction 10 inch over 1 miles equals the fraction 7 inches over z miles
B. the fraction 1 inch over 10 miles equals the fraction z inches over 7 miles
C. the fraction 1 inch over 10 miles equals the fraction 7 inches over z miles
D. the fraction z inch over 10 miles equals the fraction 7 inches over 1 miles

Best ResponseYou've already chosen the best response.2Similar example: if 1 inch = 50 miles then 3 inches on a map would mean... 1 inch/50 miles = 3 inches/x miles or just 1/50 = 3/x
