If $\frac{3}{5}$ of a bag contains 12 oranges, how many oranges are in the whole bag?

Step-by-step solution

1. Let the whole number of oranges be $x$.
2. Write the equation: $\frac{3}{5}x=12$.
3. Multiply both sides by $\frac{5}{3}$ to isolate $x$.
4. Calculate $x=12\times \frac{5}{3}=20$.
5. So there are 20 oranges in the whole bag.
