Asked by Jesica

3 gears are connected so that the two turns of the first wheel turn ii wheel nine times and the three terms of ii wheel turn the third wheel 5 times.
A. If you turn the first wheel once, how many times does the third wheel turn?
B. How many times must you turn the first wheel so that the third wheel turns 30 times?
Answered by Steve
The turns are in the ratios 2:9 and 3:5=9:15

So, they are in the ratios 2:9:15

Now things are clearer, right?
