    adding n suctracting them she would find common denominators and then simplify but my teacher says my aunt is wrong

    ah ok, well, multiplying is pretty easy: you just multiple the top number of each fraction and the bottom number of each fraction

    ah ok, so for that problem you can convert it to a non-mixed fraction

    let me re write that one 5 3/4 \[\div\] 1 2/3

    so 5 3/4 means 5 whole parts of 4 (20) + 3 parts of 4

    that is, 20/4 (since 20/4 is 5) + 3/4 = 23/4

    1 2/3 is saying "I have one set of 3's, and then 2 more"

    so that means I have 1*3/3 + 2/3 = 5/3

    now when you divide fractions, it's the same thing as multiplying by 1/(originalfraction), which basically means you multiply by the inverse of the fraction by flipping the top and bottom

    oh ok see my teacher does not explain it that thorough

    so 23/4 divided by 5/3 = 23/4 * 3/5 (I just flipped the 5 and the 3) = (23*3)/(5*4) = 69/20
