Bengal 12/20 0.60 60%
Browns 8/20 0.40 40%
To go from a fraction to a decimal-
Divide the numerator by the denominator. Example: 12 / 20 - 0. 60
To go from a fraction to a decimal-
Divide the numerator by the denominator. Example: 12 / 20 - 0. 60
To go from a decimal to a percent- Multiply by 100. Ex: 0.60 x 100 = 60 %

Start with the easiest percent to graph. Ex: 25% = 1/4, 50% = 1/2, 75% =
3/4 Ex: 33% = 1/3, 67% = 2/3
