Do these ratios form a proportion?
$91 for 84 customers
$26 for 24 customers
To determine if these ratios form a proportion, we need to compare the ratios:
$$
\frac{91}{84} \quad \text{and} \quad \frac{26}{24}
$$
First, let's simplify each ratio:
$$
\frac{91}{84} = \frac{13}{12}
$$
$$
\frac{26}{24} = \frac{13}{12}
$$
Since both ratios simplify to $\frac{13}{12}$, we can conclude that these ratios do form a proportion.
