Elizabeth has a mask collection of 420 masks. She keeps 65% of the masks on her wall. How many masks does she keep on her wall?

1. Break Down the Problem

To find out how many masks Elizabeth keeps on her wall, we need to calculate 65% of her total mask collection, which is 420 masks.

2. Relevant Concepts

To calculate a percentage of a number, we can use the formula: $\text{Percentage} = \left( \frac{\text{Percentage Rate}}{100} \right) \times \text{Total Value}$ In this case, the percentage rate is 65%.

3. Analysis and Detail

Now we can plug in the numbers: $\text{Masks on Wall} = \left( \frac{65}{100} \right) \times 420$ Let's do the calculation: $\text{Masks on Wall} = 0.65 \times 420$ Calculating it step by step:

• First, multiply 0.65 by 420: $0.65 \times 420 = 273$

4. Verify and Summarize

We've calculated that Elizabeth keeps 273 masks on her wall.

Final Answer

Elizabeth keeps 273 masks on her wall.
