  • whats wrong sally are you struggling in school
  • yes i need help in addition and subtraction in fractions 
  • 1/2 +1/2=1 whole but 1/3+1/6=3/6 so what you do is double the numerator and the denominator and you get 3/6
  • let me explain so first you look at the denomnatiors  and see if there equal in there not then convert 
  • do you understand  now
  • yeah i under stand but what about subtraction
  • example 1-3/4=1/4 because there is 4/4 in a whole so the problem is 4/4-3/4 =1/4
  • okay so here is how you do subtraction of fractions it is just like addition
  • i get it now 
  • any question
  • what do you do if there is unlike denomators 
  • 1/2 -2/4=0 because 2/4 is =to 1/2
  • so here´s how it goes 
  • i under stand now thank you
