## anonymous 3 years ago 6- 3/12 i got 23/4 but it's incorrect

1. anonymous

$6-\frac{ 3 }{ 12 }$

2. anonymous

i think you literally have a learning disability.

3. jim_thompson5910

6- 3/12 6(12/12)- 3/12 72/12 - 3/12 (72 - 3)/12 69/12 23/4 So there has to be a typo

4. anonymous

I re- wrote it @jim_thompson5910

5. jim_thompson5910

yes my work is based off what you wrote

6. jim_thompson5910

try writing it as a mixed number

7. jim_thompson5910

or in decimal form

8. anonymous

i also got that tooo

9. anonymous

2

10. anonymous

you divide 12 from 3 and you get 4 and you subtract 6 to 4 and you get 2

11. anonymous

$6-\frac{ 3 }{ 12 }$

12. anonymous

nop @ceasy007 its incorrect

13. jim_thompson5910

does it tell you type in a mixed number?

14. anonymous

$6-\frac{ 3 }{ 12 }$ @jim_thompson5910

15. jim_thompson5910

yes i know the problem

16. jim_thompson5910

that's all it says though?

17. anonymous

it says evaluate the expression @jim_thompson5910

18. jim_thompson5910

well it's 23/4 which as a mixed number is 5 3/4

19. jim_thompson5910

in decimal form it is 5.75

20. anonymous

yes totally forgot about that @jim_thompson5910

21. jim_thompson5910

which one worked?

22. anonymous

actually the answer i put in the question 23/4 which you also gave me.

23. mathstudent55

First, reduce the fraction: 6 - 3/12 = 6 - 1/4 = 6/1 - 1/4 Now find a common denominator: the LCD of 1 and 4 is 4 24/4 - 1/4 = 23/4 = 5 3/4

24. jim_thompson5910

oh, so why didn't it work the first time?

25. jim_thompson5910

how odd

26. anonymous

i thought i would only have to go 23/4 but you can reduce that to 5 3/4

27. anonymous

@jim_thompson5910

28. jim_thompson5910

it doesn't reduce, it converts to that

29. anonymous

yes that's what i meant

30. jim_thompson5910

i gotcha
