To determine the percent of a number do the following steps:

1 Multiply the number by the percent (e.g. 87 * 68 = 5916)

2 Divide the answer by 100 (Move decimal point two places to the left) (e.g. 5916/100 = 59.16)

3 Round to the desired precision (e.g. 59.16 rounded to the nearest whole number = 59)

1st work out the difference between 2 numbers

2nd increase ~ new number ~ original number

3rd divide increase by original number then multiply the answer by 100

4th % increase = Increase divides by original number x 100
