    The 60% of adults who like pizza was found by dividing the adults who like pizza (0.36) by the total adults (0.60) : 0.36 / 0.6 = 0.6 = 60%

    To find the percent of children that like pizza divide 0.29 by 0.40:

    0.29 / 0.40 = 0.725 = 72.5%, which is about 70%

    The answer would be C. A greater percentage of children (about 70%) prefer pizza.
