1. 1. Set up in a proportion: 36/x = 40/100. 40x = 3600, x=90. 2. 25% decrease, since the difference, 10, is 1/4 of 40. 3. To go from percent to decimal, move the decimal point over 2 to the left. 180.0% = 1.8 (move to the right when going from decimal to percent) 4. Put any percent over 100 to get the fraction, then reduce. 8/25. 5. Use Microsoft Excel's PMT function to figure that one out. 6. If something is 20% off, the sale price is 80% of the original. .8 * 125 = 100 7. A quick way to do this is take 10% of 60, which is 6, and triple it, to 18. Same as 5.
