The school's total attendance is 449, there are 81 present in math class, what percent of the total attendance is the attendance in the math class (to the nearest tenth) ? 6% 18% 55% 82%

100%/x%=449/81

(100/x) * x = (449/81) * x - we multiply both sides of the equation by x

100=5.5432098765432*x - we divide both sides of the equation by (5.5432098765432) to get x

100/5.5432098765432=x

18.04008908686=x

x=18.04008908686

1) Percentage = (Math Class / Total Attendance) x 100

thus ... Percentage = 81 / 449 = 0.18 x 100 = 18%

2. 1/8 x 6 = 6/8ths = 6 pieces of cake
