it is estimated that at the turn of the 20th century, one farmer in the U.S could feed 25 people, whereas today, the ratio is about 1 to 130. How many farmers would it take today to feed 2600 people?
Please help i don't even know how to do this problem!

    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

    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.
