13%:17%

The ratio \( 13\% : 17\% \) can be simplified by removing the percentage signs and writing it as \( 13 : 17 \).

This ratio cannot be simplified further because 13 and 17 are both prime numbers, and they have no common factors other than 1.

If you need to express this ratio in decimal form or as a fraction, it can be done as follows:

1. As a fraction: \[ \frac{13}{17} \]

2. In decimal form: \[ \frac{13}{17} \approx 0.7647 \quad (\text{rounded to four decimal places}) \]
