Answer:
27
Step-by-step explanation:
In this case we associate in total value from 225 to 100%, and they tell us that foreign currencies represent 88%, therefore, in quantity this would be:
225 * 88/100
198
The rest of the coins would then refer to the other coins I collect, which would be:
225 - 198 = 27
That is, 27 coins are the remaining coins.
