i do not understand how to multiply and divide fractions
anonymous
  • anonymous
umm how did ur aunt do it?
anonymous
  • anonymous
adding n suctracting them she would find common denominators and then simplify but my teacher says my aunt is wrong
anonymous

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

like this problem 5 3/4 divided by 1 2/3
sandra
  • sandra
ah ok, so for that problem you can convert it to a non-mixed fraction
anonymous
  • anonymous
let me re write that one 5 3/4 \[\div\] 1 2/3
sandra
  • sandra
so 5 3/4 means 5 whole parts of 4 (20) + 3 parts of 4
sandra
  • sandra
that is, 20/4 (since 20/4 is 5) + 3/4 = 23/4
anonymous
  • anonymous
how do I do that?
sandra
  • sandra
1 2/3 is saying "I have one set of 3's, and then 2 more"
sandra
  • sandra
so that means I have 1*3/3 + 2/3 = 5/3
sandra
  • sandra
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
anonymous
  • anonymous
oh ok see my teacher does not explain it that thorough
sandra
  • sandra
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
sandra

and that is the answer
