now you tell me what are we supposed to do here ^_^
anonymous
  • anonymous
this one is alil more challenging
anonymous
  • anonymous
alright, first get them to have the same denominator ^_^

looks like you need common denominators

anonymous
  • anonymous
so what will you do now rsan? ^_^
anonymous
  • anonymous
i have no clue im stuck
anonymous
  • anonymous
we need to get the fractions to have the same denominators, so what to do? do we multiply both fractions or only one?
anonymous
  • anonymous
both
anonymous
  • anonymous
excellent now which are you going to multiply with 10 and which are you going to multiply with 9?
anonymous
  • anonymous
thinking...............................
anonymous
  • anonymous
here, the question is : \[\frac{7}{9} - \frac{1}{10}\] hmm what to do?
anonymous
  • anonymous
how will i get 9 into an even number like 10 can get even numbers
anonymous
  • anonymous
:) all you have to do is multiply the first fraction with 10 and the other fraction with 9 to get the same denominator which is = 90 ^_^
anonymous
  • anonymous
wow i feel blind for not cathing that lol
anonymous
  • anonymous
so after that we'll have :\[\frac{10}{10} \times \frac{7}{9} - \frac{1}{10} \times \frac{9}{9} = \frac{70 - 9}{90}\] continue ^_^
anonymous
  • anonymous
dw, it happens ^_^
anonymous
  • anonymous
61/90
anonymous
  • anonymous
good boy ^_^
anonymous
  • anonymous
how can i reduce that?
anonymous
  • anonymous
now I have a questin for you :)
anonymous
  • anonymous
it cannot be reduced, try :)
anonymous

\[\frac{2}{13} - \frac{1}{2}\]? what to do ^_^? think and give me the answer
anonymous
  • anonymous
sweet i tried it.
anonymous
  • anonymous
so , can it be reduced?
anonymous
  • anonymous
now try the question I gave you, remember the 3 rules: 1) Get the same denominators 2) calculate 3) simplify, if can :)
anonymous
  • anonymous
i got 9/26
anonymous
  • anonymous
so far lol
anonymous
  • anonymous
excellent, but becareful of the sign
anonymous
  • anonymous
is it 9/26 or -9/26?
anonymous
  • anonymous

anonymous
  • anonymous
good, because?
