Two gears have 72 teeth altogether. The larger gear has three times as many teeth as the smaller gear. Find the number of teeth on each gear

Question

we have to find larger and smaller gear

 

Answer 1

Let x = the number of teeth on the smaller gear

Let 3x = the number of teeth on the larger gear

x + 3x = 72

4x = 72

x = 18

3x = 54
