Answer

Explanation:

Step1: Identify the total - amount and per - student amount

The total number of baking soda boxes is 18, and each student uses $\frac{2}{3}$ of a box.

Step2: Set up the division formula

We need to find out how many $\frac{2}{3}$ are in 18. The formula is $18\div\frac{2}{3}$.

Step3: Use the rule of dividing by a fraction

Dividing by a fraction is the same as multiplying by its reciprocal. So $18\div\frac{2}{3}=18\times\frac{3}{2}$.

Step4: Calculate the result

$18\times\frac{3}{2}=\frac{18\times3}{2}=\frac{54}{2} = 27$.

B. 27
