How many containers are needed to store the leftover sugar?

Answer 1

Answer:

21 containers

Step-by-step explanation:

When dividing fractions, you can multiply by the inverse of the fraction. For example, in this case, $14 divided by \frac{2}{3} = \frac{14}{1}x\frac{3}{2}$. Whoever drew the calculations made the mistake of forgetting to flip the second fraction.

The actual solution of the problem is 42/2, or 21/1. 21 containers are needed to store the sugar.
