1. Problem Description

We are asked to determine which sign ($>$, $<$, or $=$) makes the statement $\frac{45}{80} \text{ ? } 67\%$ true.

2. Solution Steps

First, we convert the fraction $\frac{45}{80}$ to a decimal:

$\frac{45}{80} = \frac{9}{16} = 0.5625$.

Next, we convert the decimal to a percentage by multiplying by 100:

$0.5625 \times 100 = 56.25\%$.

Now, we compare $56.25\%$ to $67\%$. Since $56.25 < 67$, we have $56.25\% < 67\%$.

Thus, $\frac{45}{80} < 67\%$.
