Hannah and francine have 120. hannah and peter have 230.peter has 6 times as much money sa francine.how much money does hannah have?

  • math - ,

    h+f = 120
    h+p = 230
    p = 6f

    since p=6f,

    h+f = 120
    h+6f = 230

    subtract top from bottom to get

    5f = 110
    f = 22
    so, h=98

    Hannah has 98

  • math - ,

    Where does the 5f come from??

    I understand you subtract, but what determines that you should divide 110 by 5?
