The first thing to do is rewrite the question in fraction form. In this case we want to know 190 out of 200 as a percentage. This can be written as 190/200, which calculates to 0.95. To convert from decimal to percentage, you multiply by 100. In this case, 0.95x100 = 95. Thus 190 is 95% of 200.
190 x 100 / 12.5 = 190 x 8 = 1520
0.0625x190=11.875. 6.25% of 190 is 11.875.

Just multiply 190 by 1.12 and you will have your answer. This is how I get the "1.12". The final amount will be 190 dollars PLUS twelve percent of 190 dollars. This can be expressed: 190 dollars (1 PLUS 12 percent). 190 ( 1 + .12). The 190 times 1 gives you, not surprisingly, the whole original 190 dollars. The 190 times .12 gives you the twelve percent. So 190 X 1.12 is a simple calculation that will give you the answer. We don't normally think that multiplying something by one could ever be the least bit useful, but it is useful.
