It looks like the image shows a gear mechanism, where gear A meshes with gear B. Below the gears, there's a table to be completed with values related to the number of teeth or turns of these gears.

In the table, I can see two numbers, 20 and 45. These likely represent the number of teeth on gears A and B, respectively.

To complete the table, you'll need to determine the gear ratio between A and B. The ratio of the number of teeth on gear A to the number of teeth on gear B dictates how many turns one gear makes relative to the other.

The formula for the gear ratio \( R \) is:

\[
R = \frac{\text{Teeth on Gear B}}{\text{Teeth on Gear A}} = \frac{45}{20} = 2.25
\]

This means for every 1 turn of Gear A, Gear B makes 2.25 turns.

Let me know if you'd like more details on any of the calculations, or have any questions!

Here are 5 related questions:
1. How do you calculate the gear ratio in complex gear systems?
2. If Gear A had 40 teeth and Gear B had 20 teeth, how many turns would Gear B make for one turn of Gear A?
3. How does the size of a gear affect its rotational speed in a gear system?
4. What is the significance of the gear ratio in mechanical systems?
5. How does increasing the number of teeth on one gear affect the overall mechanical advantage?

**Tip:** Always check if the gears are meshing properly by ensuring that the number of teeth on each gear is an integer multiple to prevent slippage.

Complete the table for the gear mechanism with gear A and gear B, given that gear A has 20 teeth and gear B has 45 teeth.

Learn how to calculate the gear ratio for a system where gear A has 20 teeth and gear B has 45 teeth. This problem involves concepts of rotational mechanics and proportions, making it suitable for students in Grades 7-10.
