  1. If there were x male teachers, then we know that

    f = m+4, so
    (m + m+4) * 60 = 1200

    Now just find m

  2. 1200 /60= 20 teachers.
    20/2=10.
    there were 4 more female teachers so 10 plus 4 =14.
    and 10-4=6.
    so there were 6 male teachers.

  3. $1200 ÷ $60 ⇒ To find out the number of teachers
    = 20 teachers
    = 20 ÷ 2 = 10

    There were 4 more female teachers. So,

    10 + 4 = 14
    20 - 14 = 6

    Male teachers = 6
    Female teachers = 14
