## anonymous 5 years ago 7/9 - 1/10

1. anonymous

now you tell me what are we supposed to do here ^_^

2. anonymous

this one is alil more challenging

3. anonymous

alright, first get them to have the same denominator ^_^

4. anonymous

looks like you need common denominators

5. anonymous

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

6. anonymous

ll

7. anonymous

so what will you do now rsan? ^_^

8. anonymous

i have no clue im stuck

9. anonymous

we need to get the fractions to have the same denominators, so what to do? do we multiply both fractions or only one?

10. anonymous

both

11. anonymous

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

12. anonymous

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

13. anonymous

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

14. anonymous

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

15. 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 ^_^

16. anonymous

wow i feel blind for not cathing that lol

17. 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 ^_^

18. anonymous

dw, it happens ^_^

19. anonymous

61/90

20. anonymous

good boy ^_^

21. anonymous

how can i reduce that?

22. anonymous

now I have a questin for you :)

23. anonymous

it cannot be reduced, try :)

24. anonymous

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

25. anonymous

sweet i tried it.

26. anonymous

so , can it be reduced?

27. anonymous

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

28. anonymous

i got 9/26

29. anonymous

so far lol

30. anonymous

excellent, but becareful of the sign

31. anonymous

is it 9/26 or -9/26?

32. anonymous

-9/26

33. anonymous

good, because?

34. anonymous

4-13 is -9

35. anonymous

^_^ well done
