    Answer:

    decimal = 3.25

    fraction = \frac{13}{4}

    Step-by-step explanation:

    since x and y are the only 2 variables being expressed in the question then it makes “z” irrelevant.

    Therefore, you just need to plug in x and y into your question

    (\frac{1}{2} × (2)) +( \frac{3}{4} × (3)) = 1 + 2.25 = 3.25 or \frac{13}{4}
