Take The Original Number, And Subtract The New Number From It.
So 16 is our original number, and 12 our new number: When there is an increase in the percentage, add the increased percentage in $$100$$, and find the original value. Divide final number by decimal:
There Are Two Types Of Problems In Reverse Percentages:

1 + 0.06 = 1.06 1+0.06 = 1.06. For the math below, discount is a percentage and cost will be a dollar figure. Much like in the previous examples, the most common errors involve arithmetic.
