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?

Respuesta :

7:3
259:?

259/7 = 37

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

Answer:

111

Step-by-step explanation:

7 : 3

259 : [tex]\frac{259}{7} \times 3[/tex]

Or  [tex]\frac{7}{3}=\frac{259}{x} [/tex]  ⇒  [tex]x=\frac{259}{7} \times 3=111[/tex]
