mark finished 3/5 of his chocolate milk. sara finished 5/6 of her chocolate milk. how much more chocolate milk did sara finish than mark? show your work.

3/5
3•6/5•6
18/30

5/6
5•5/6•5
25/30

25-18=7

She finished 7/30 more than him just simplify that by doing 30 divided by 7

3/5 and 5/6 must have the same denominator so 3/5 would become 18/30 and the 5/6 would be come 25/30 and u then subtract 25 from 18 and get 7

So the answer would be 7/30

I’m not absolutely sure but i think it’s 7x6x5x4x3x2=5040 because as the first character you can take any of the 7 given then you are left with 5 then 6 then 4 etc.
