Answer:
- The diagram bar is attached.
- Addition equation: 
- Multiplication equation: 
- How are the equation related? Each equation shows 3 groups of 7.
Step-by-step explanation:
We know that Jan buys 3 bags of beads and each bag contains 7 beads, then, you can draw the bar diagram shown attached.
Observe that the diagram has 3 blocks (each block represents a bag of bead) and there is a number 7 inside of each block (which is the number of beads contained in a bag).
Therefore:
- Add the numbers inside the blocks in order to get the addition equation that shows the number of beads Jan buys. This is:

- Multiply 3 blocks by 7 in order to get multiplication equation that show the number of beads Jan buys:

The equations are related. Each one shows 3 groups of 7.
