225 is composite. The last digit is 5, so it is divisible by 5. Therefore it is composite. In fact, it is 15 squared. In contrast, a prime number is a number that is divisible only by 1 and itself; it has no other factors. The factors of 225 are 1, 3, 5, 9, 15, 25, 45, 75, and 225. Therefore, 225 is a composite number.

16% of 225= 16% * 225= 0.16 * 225= 36

12% of 225 = 12% * 225 = 0.12 * 225 = 27

12% of 225= 12% * 225= 0.12 * 225= 27

The prime factorization of 225 is 3 * 3 * 5 * 5 or 3^2 * 5^2.To work out the prime factors of a number, it helps to divide it by obvious factors first. In this case, the number ends in a 5, so we know we can divide it by 5. Do this and we are left with 45. This is known from times tables to be 9x5, and 9 can be split up into 3 and 3. Thus we have finished prime factorizing 225. The prime factors of it are 5, 5, 3 and 3.3 x 3 x 5 x 5 = 225
