    Answer:

    10

    Step-by-step explanation:

    Set up the following proportion.

    2 questions /15 minutes = x questions / 75 minutes.

    Notice that both ratios are set up the same way — questions / time. All proportions are set up the same way.

    Mulltiply both sides by 75

    2 * 75 / 15 = x

    2 * 5 = x

    x = 10

    She would be able to solve 10 problems in 75 minutes.

    10.

    Because the ratio is how many problems:How much time so it is 2:15

    Multiply each side by 5 10:75

    So that means 10 problems in 75 minuets.

    HOPE THIS HELPED!!!
