looks like you need common denominators

madest pickup line^ , had a little laugh for no real reason :P

- anonymous

ll

- anonymous

so what will you do now rsan? ^_^

- anonymous

i have no clue im stuck

- 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

both

- anonymous

excellent now which are you going to multiply with 10 and which are you going to multiply with 9?

- anonymous

thinking...............................

- anonymous

here, the question is :
\[\frac{7}{9} - \frac{1}{10}\]
hmm what to do?

- anonymous

how will i get 9 into an even number like 10 can get even numbers

- 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

wow i feel blind for not cathing that lol

- 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

dw, it happens ^_^

- anonymous

61/90

- anonymous

good boy ^_^

- anonymous

how can i reduce that?

- anonymous

now I have a questin for you :)

- anonymous

it cannot be reduced, try :)

- anonymous

\[\frac{2}{13} - \frac{1}{2}\]?
what to do ^_^? think and give me the answer

- anonymous

sweet i tried it.

- anonymous

so , can it be reduced?

- anonymous

now try the question I gave you, remember the 3 rules:
1) Get the same denominators
2) calculate
3) simplify, if can :)

- anonymous

i got 9/26

- anonymous

so far lol

- anonymous

excellent, but becareful of the sign

- anonymous

is it 9/26 or -9/26?

- anonymous
