Question

clue 3: there are 12 lightbulbs arranged in 3 equal rows. how many lights do you need to turn on? 4 6 10

Explanation:

Step1: Determine the number of bulbs per row

We know there are 12 lightbulbs arranged in 3 equal rows. To find the number of bulbs in each row, we use division. The formula for the number of bulbs per row ($n$) is $n=\frac{\text{Total number of bulbs}}{\text{Number of rows}}$. Substituting the given values, we have $n = \frac{12}{3}$.

Step2: Calculate the result

Calculating $\frac{12}{3}$, we get 4. So each row has 4 bulbs, which means we need to turn on 4 lights.

Answer:

4
