    2/3 and 4/9

    Doing cross multiplication,

    2 x 9 and 3 x 4

    = 18 and 12

    Since 18 is not equals to 12

    Therefore 2:3 and 4:9 are not in proportion.

    No, He is not right.

    Two ratios a:b and c:d are in proportion only if a*d = b*c 

    and in this case this is not possible.
