Final answer:
To find the exchange rate from Gammas to Alphas, multiply the given exchange rates and simplify the fraction.
Step-by-step explanation:
To find the exchange rate from Gammas to Alphas, we need to consider the two given exchange rates. Let's say the exchange rate from Alphas to Betas is 2 Alpha coins to 3 Beta coins, and the exchange rate from Betas to Gammas is 4 Beta coins to 5 Gamma coins. To find the exchange rate from Gammas to Alphas, we can multiply these two exchange rates: (2 Alpha coins / 3 Beta coins) multiplied by (4 Beta coins / 5 Gamma coins). Simplifying this fraction gives us (8 Alpha coins / 15 Gamma coins). Therefore, the exchange rate from Gammas to Alphas is 8 Alpha coins to 15 Gamma coins.
