Explanation:

Question 1

Step1: Multiply inputs for total use

$\text{total electricity use (kw)} = \text{electricity use per house (kw/house)} \times \text{number of houses (houses)}$

Question 2

Step1: Divide magazines by boxes

$\text{magazines per box (mag/box)} = \frac{\text{number of magazines (mags)}}{\text{number of boxes (boxes)}}$

Question 3

Step1: Divide pipe by streets

$\text{water pipe per street (ft/st)} = \frac{\text{total water pipe (ft)}}{\text{number of streets (st)}}$

1. Inputs: electricity use per house (kw/house), number of houses (houses); Action: use conversion factor (multiplication)
2. Inputs: number of magazines (mags), number of boxes (boxes); Action: division (the top dropdown option, representing $\div$)
3. Inputs: total water pipe (ft), number of streets (st); Action: division (the dropdown option representing $\div$)
