15. enVision \( { }^{\ominus} \) STEM Mary saw two poison dart frogs. One was \( \frac{7}{8} \) inch long and the other was \( \frac{5}{8} \) inch long. How much longer was one than the other?

To find out how much longer one poison dart frog is than the other, you subtract the lengths: \( \frac{7}{8} \) inch - \( \frac{5}{8} \) inch = \( \frac{2}{8} \) inch. Simplifying \( \frac{2}{8} \), you get \( \frac{1}{4} \) inch. So, one frog is \( \frac{1}{4} \) inch longer than the other! Now, you might be wondering about the fascinating nature of poison dart frogs. Did you know that their vibrant colors act as a warning to predators about their toxicity? This incredible adaptation showcases nature’s way of balancing beauty with survival. They're small but pack a punch!
