Answer:
10 teeth must go on the driven gear
Step-by-step explanation:
Let the number of teeth be x
In order for the new product to maintain the same ratio as the old the ratio must remain the same. This means that
17:5 = 34:x
∴ 10 teeth must go on the driven gear
hence ratio = 34:10
8/10 = 0.8
Therefore, 0.8 (8/10) is put on the number line shown below.
