a piece of rope 3m 66 m long was cut into 2 pieces. the longer piece was twice as long as the shorter piece. What was the length of the longer piece?

  • math - ,

    If 3m 66m mean 3 m 66 cm then:

    3 m 66 cm = 3.66 m


    L = Longer piece

    S = Shorter piece


    L = 2 S

    L + S = 3.66 m

    2 S + S = 3.66 m

    3 S = 3.66 m Divide both sides by 3

    S = 3.66 m / 3

    S = 1.22 m = 1 m 22 cm

    L = 2 S = 2 * 1.22 m = 2.44 m = 2 m 44 cm
