He collected a total of 225 . If ​68% of the stamps he collected were​ foreign, how many other stamps did he​ collect?
MissTica

Answer:

72 stamps

Step-by-step explanation:

First, we're looking to find the number of stamps that AREN'T foreign, so we have to subtract 68% from 100%.

  • 100% - 68%
  • 32%

Now, we know that 32% of the stamps are NOT foreign. So, next, we:

  1. Multiply 32 by 225.
  2. Divide the product of 32 and 225 by 100
  • 32*225
  • 7200
  • 7200/100
  • 72

Therefore, the answer is 72 stamps.
