Craig collects coins. He collected a total of 225 coins. If 88% of coins he collected were foreign, how many other coins did he
agasfer [191]

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.
