what is it?

2. anonymous

HERE IS PROBLEM BELOW.. A Parent died and left an estate to four children. One inherited 1/9 of the estate, the Second inherited 5/81, and the third inherited 17/27. How much did the Fourth Inherited? Type a simplified fractions

3. anonymous

ok first you need to turn all the fractions to the same denominator do you know how to do that?

4. anonymous

no i dont know how too do that.. can you help me with that

5. anonymous

1/9+5/81+17/27 =

6. anonymous

Can you help me with the Answer. Also can you Explain how you got the answer and walk me through step by step.

7. anonymous

yes that would be the equation but in order to add the you need all denominaters the same because it makes it much easier soooo..... all of them can be changed to 81 1/9 times by 9 is 9/81 and then 5/81 doesn't need to be changed and then 17/27 times by three is 51/81 so it would be $\frac{ 9 }{ 81 } + \frac{ 5 }{ 81 } + \frac{ 51 }{ 81 } =$

8. anonymous

can you understand that ^^^^^

9. anonymous

since i already typed that up

10. anonymous

so do I add all of this together and then simplify

11. anonymous

yes, that would be the next step

12. anonymous

13. anonymous

yes and then you would subtract that from 81/81

14. anonymous

because 81/81 is the whole and then your subtracts everyone else s inheritance from that to find out the fourth persons.

15. anonymous

-16/81

16. anonymous

how did you get a negative

17. anonymous

it is 81/81-65/81

18. anonymous

its positive sorry 16/81

19. anonymous

so will i take 16/81- 17/27

20. anonymous

or 17/81

21. anonymous

why do you think you would do that?

22. anonymous

oops. sorry i just realized that was the answer lol Math isnt my cup of tea

23. anonymous
