Each cupcake takes 3/10 of a cup of frosting. If Amy wants to make 15 cupcakes, how much frosting will she need?

To determine how much frosting Amy will need for 15 cupcakes, we can multiply the frosting required for each cupcake by the number of cupcakes.

Each cupcake takes \( \frac{3}{10} \) of a cup of frosting, and Amy wants to make 15 cupcakes:

\[
\text{Total frosting} = 15 \times \frac{3}{10} = \frac{45}{10} = 4.5 \text{ cups of frosting}
\]

So, Amy will need 4.5 cups of frosting to make 15 cupcakes.

1. If each cupcake took 1/2 cup of frosting, how much would Amy need for 10 cupcakes?
2. How many cupcakes can Amy frost if she has 6 cups of frosting?
3. What if Amy wants to make 20 cupcakes but each uses 1/4 cup of frosting? How much would she need?
4. If Amy only has 3 cups of frosting, how many cupcakes can she frost if each uses 3/10 cup?
5. How much frosting will she need if she decides to make twice as many cupcakes, each still using 3/10 of a cup?

**Tip**: When dealing with fractions in problems, it's often helpful to multiply the numerator directly and then simplify!
