Explanation:

Step1: Convert fraction to percent

First, convert $\frac{3}{8}$ to a percent. To do this, divide 3 by 8: $3\div8 = 0.375$. Then multiply by 100 to get the percentage: $0.375\times100 = 37.5\%$.

Step2: Find the percentage of 640

Now, find $37.5\%$ of 640. The formula for finding a percentage of a number is $\text{Percentage} \times \text{Number}$. So, $0.375\times640 = 240$. But wait, the first part is to rewrite the fraction problem as a percent problem, so we first find what percent $\frac{3}{8}$ is, which is $37.5\%$, and then we can say "Find $37.5\%$ of 640". But if we just need the percentage value to rewrite the problem, the percentage is $37.5\%$. Wait, the question says "Rewrite this fraction problem as a percent problem. Find $\frac{3}{8}$ of 640. Find [ ]% of 640." So we need to find what percent $\frac{3}{8}$ is. So step by step:

1. Calculate $\frac{3}{8}$ as a decimal: $3\div8 = 0.375$.
2. Convert decimal to percent: $0.375\times100 = 37.5\%$.

So the percentage to fill in the box is $37.5$.

Answer:

$37.5$
