Question

From the beginning of cross- country season to end, Tisha reduced her time by 17%, Ankara reduced her by 1/6, Juanita reduced hers by 4/25, and Julia reduced hers from 16:00 to 13:30. Who reduced her time by the greatest percent?

Answer 1

Divide the numerator by denominator: 1/6=.1667; 4/25=.16. Change to percents by moving decimal: Ankara: 16.6% or 17%; Juanita: 16%. Find the time difference: 16:00-13.30=2:30. Divide by 100: 2.5/100=.025. Change to percent: Julia: 2.5% or 3%. Tisha reduced her time the most :)
