    23 students

    Step-by-step explanation:

    6 boys: 11 girls

    x boys: 15 girls Add in the new equation

    15/11 is about 1.36 Find the scale factor used

    6 x 1.36 is about 8.18 Multiply the scale factor by the known amount of boys

    Since we are adding students, there can't be part of a student.

    6 boys: 11 girls

    8 boys: 15 girls

    There is a total of 23 students in the school play.
