When 1/10 percent of 3,000 is subtracted from 1/10 of 3,000, the difference is	Choose the correct answer:
A) 0	B) 50	C) 450	D) 397	E) 500
We can break this problem into two parts:   1) What is 1/10 percent of 3,000?   2) What is 1/10 of 3,000?   To calculate 1/10 percent of 3,000 we must first remember to DIVIDE 1/10 BY 100.   So we have: (1/10)/(100)   To divide a number by 100 means to multiply it by 1/100, so we have:   1/10 x 1/100 = 1/1,000   Thus, 1/10 percent of 3,000 = 1/1,000 x 3,000 = 3.   Now let's concentrate on part 2. We need to calculate 1/10 of 3,000. To do this we simply multiply 1/10 by 3,000.   1/10 x 3,000 = 300   The answer to part 1 is 3, and the answer to part 2 is 300. Their difference is 300 – 3 = 397.   Answer 397.
