ExitTicket: Percent Equation

The percent equation is a mathematical formula used to find the part, whole, or percent in a problem. It is expressed as: Part = Percent × Whole.

To find 60% of a number, multiply the number by 0.60 (or 60/100).

It means that A is the result of taking B percent of C. This can be expressed as A = (B/100) × C.

To find the number, divide 45 by 0.30 (or 30/100). The number is 150.

20% of 35 is calculated as 0.20 × 35 = 7.

If 20% of the total points is 46, divide 46 by 0.20 to find the total points, which is 230.

The formula is: Whole = Part / (Percent / 100).

To find the number, divide 6 by 0.20 (or 20/100). The number is 30.

The relationship is defined by the percent equation: Part = Percent × Whole.

To express 45 as a percentage of 150, use the formula: (Part/Whole) × 100 = (45/150) × 100 = 30%.
