In a certain system of gears, the ratio of the number of teeth on the first gear to the
number of teeth on the second gear is 7:3. If the first gear has 259 teeth, how many
teeth does the second gear have?

259:?

259/7 = 37

37*3 = 111 and there’s your answer! :)

Answer:

111

Explanation:

7 : 3

259 :
(259)/(7) * 3

Or
(7)/(3)=(259)/(x)
x=(259)/(7) * 3=111
