    We can represent this situation by the equation 2x+4x+5x=33.

    Then 11x=33, and x = 3.

    Then the children's ages are in the ratio 2x:4x:5x, or 2 (3) : 4 (3) : 5 (3), or

    6:12:15.

    Do these 3 ages add up to 33? 6 + 12 + 15 = 33? YES!

    The children's ages are 6, 12 and 15 years respectively.
