    Trying to get 3:1

    Divide 236 by four=59

    Then times 59 by 3

    The ratio now is 177:59

    3:1

    Let x be the number of girls and y the number of boys

    1st equation: x + y = 236

    But for each y (boy), there 3x (girls)

    2nd equation: y = 3x

    Now solve:

    |x + y = 236

    | y = 3x

    |x + y = 236

    | - 3x + y = 0

    You'll find x (girls) = 59 and y (boys) = 177
