    Step-by-step explanation:

    student teacher ratio of 5:2 ... added = 7

    so students make up 5/7 of the total people and teachers make up 2/7 of the total people.

    Last year ... 56 people

    students : 5/7 * 56 = 280/7 = 40 students

    teachers : 2/7 * 56 = 112/7 = 16 teachers

    this year ... 70 total people

    students : 5/7 * 70 = 350/7 = 50 students

    teachers : 2/7 * 70 = 140/7 = 20 teachers
