One way to do this is is by using a proportion. Cross multiply and solve for x.
1/130 = x/2600
130x = 2600
x = 2600 / 130
x = 20
1/130 = x/2600
130x = 2600
x = 2600 / 130
x = 20

This is just a proportion problem.
2600 people x (1 farmer/130 people) = ? farmers. See how the units cancel. people cancels people; you have converted people to farmers.
