Three frogs are trying to hop across the road. The first frog takes 4 times as many hops as the second. The second frog takes twice as many as the third. If the three frogs took a total of 99 hops, how many hops did it take the second frog to cross the road? Think carefully first, then make a decision:
User
Let x represent the number of hops it took the third frog. The second frog:2x. First frog:4(2x) = 8x. Total:x + 2x + 8x = 99. 11x = 99. x = 9. Second frog:2(9) = 18 hops. So, the answer is 18.
