    Step by step explanation:

    20p coins = 640 - 640 * (3/8+3/8) = 640 * (-16/8) = 640 * 2/8=640*1/4=160

    160 off 20p coins

    Step-by-step explanation:

    1 p, 20 p, 5 p coins 1 p = 3/8 of the bag 5 p = 1 p = 3/8 of the bag total coins = 640

    20 p coins = 640 - 640 * (3/8+3/8) = 640 * (1 - 6/8) = 640 * 2/8 = 640 * 1/4 = 160
