Hello, I'm glad to answer this question for you. Thai baht means Thai baht in Thailand. Thai baht is the official currency of Thailand and is issued by the Bank of Thailand. Thai baht is also the gold unit of measurement in Thailand's jewelry industry. One Thai baht is equivalent to 15.244 grams. As shown in the figure below:

Then let's look at the exchange rate between Thai baht and RMB. 1 Thai baht =0. 1898 RMB, then we can easily calculate our answer according to this simple formula. According to the formula, foreign exchange amount × bank buying exchange rate = functional currency amount. Then we can clearly know that the foreign exchange gold coin is 2860 baht, and the exchange rate for banks to buy yen today is 1 baht =0. 1898 RMB.

So the amount in functional currency is 2860× 0. 1898 = 542.828 yuan. Since the exchange rate changes all the time, it should be calculated according to the exchange rate at that time. This is the answer we have worked out now. I hope my answer is helpful to you.
