    Cross multiply.

    75 / x = 25 / 35

    25x = 35 (75)

    25x = 2625

    /25 / 25

    x = 105

    Therefore 105 students liked skating.

    Proof:

    105 + 35 = 140.

    140 * 0.75 = 105

    140 * 0.25 = 35

    140 (total) split into quarters.

    35 + 35 + 35 + 35 = 140

    35 + 35 + 35 = 105 (3 quarters liked)

    35 = 35 (1 quarter disliked)
