The ratio of the length of square A to the length of square B is 3:5. If the length of square A is 18 meters, what is the perimeter of square B

Number*percent in a decimal 200 * .42 = 84

4/90 x 100 = 4.4 recurring (that is, 4.4444..) percent.

It is: (68/80)*100 = 85%

To calculate the Percent to Plan, you can first substitute the variable X for the percent and the variable Y for the Plan, and then you can solve for the end rate of percent to plan easily.
