    Total tarts = 45

    Step-by-step explanation:

    Let x be the total tarts

    Pineapple tarts = 1/5

    So, coconut tarts are 4/5

    She gave 1/2 of the coconut tarts to her uncle,

    1/2 * 4/5 = 4/10 = 2/5

    So, to find x

    4/5x - 2/5x = 18

    2/5x = 18

    2x = 18 x 5

    x = 90/2

    x = 45
