Question

Nathaniel has a toy car collection of 480 toy cars. He keeps 216 of the toy cars on his wall. What percentage of Nathaniel's toy car collection does he keep on his wall?

Answer 1

To find out what percentage of Nathaniel's toy car collection he keeps on his wall, we can use the formula for percentage:

\[
\text{Percentage} = \left( \frac{\text{Part}}{\text{Whole}} \right) \times 100
\]

In this case, the "Part" is the number of toy cars kept on the wall (216), and the "Whole" is the total number of toy cars (480).

Substituting the values into the formula:

\[
\text{Percentage} = \left( \frac{216}{480} \right) \times 100
\]

First, we calculate the fraction:

\[
\frac{216}{480} = 0.45
\]

Now, multiplying by 100 to find the percentage:

\[
0.45 \times 100 = 45
\]

Thus, Nathaniel keeps 45% of his toy car collection on his wall.

The final answer is:

\[
\boxed{45\%}
\]
