To find the percentage of Ella's mask collection that she keeps on her wall, we can use the following formula:
\[
\text{Percentage} = \left( \frac{\text{Part}}{\text{Whole}} \right) \times 100
\]
In this case:
- Part = 144 (the number of masks on her wall)
- Whole = 400 (the total number of masks in the collection)
Plugging in the values:
\[
\text{Percentage} = \left( \frac{144}{400} \right) \times 100
\]
Calculating \(\frac{144}{400}\):
\[
\frac{144}{400} = 0.36
\]
Now, multiplying by 100 to convert to a percentage:
\[
0.36 \times 100 = 36
\]
Therefore, Ella keeps **36%** of her mask collection on her wall.
