    I added 1.25 and 3 and got 1.28
    Then I multiplyed by 5. I don't know If i did it right or If I'm suppose to do that

    1.25 + 3 = 4.25

    4.25 / 2 = 2.125

    2.125 * 5 = ?

    Does / mean to divide and * mean to multiply?

    Yes.

    Dont I divide it with 5? so it would be 4.25/5?

    No. You need the total amount of sugar for 5 batches of brownies.

    Think about it. One recipe alone calls for 3 cups of sugar. Five recipes can't be less than 3 cups.
