  1. Step-by-step explanation:

    here,

    total dancers= 80

    ratio= 5:16

    let the ratio of 7th grade dancers be 5x and total dancers be 16x

    since, 16x includes the 5x which needs to be taken out, other dancers= 16x-5x= 11x

    Now,

    5x+11x= 80

    16x= 80

    x= 80/16=5

    therefore, number of 7th grade dancers= 5x= 5×5= 25
