The ratio of swimmers to runners in a biathlon is 5:2. There are 60 swimmers. How many runners are there?
Select one:
a. 5
b. 24
c. 25
d. 60

Respuesta :

5/2 = 60/x
cross multiply
5x = 120
x = 120/5
x = 24 <====
First you set your equation like this 
r:60
5:2

you divide 60 and 2 to see how much the difference is
then you multiply 5 and the answer to 60/2 to get R. Hope This helps
