## HayleyWhite17 3 years ago Create three fractions by replacing the word ‘blank’ in each fraction with a variable or number. You can use the same value or three different replacement values. Explain all the work in simplifying your new addition problem. 3 over blank plus blank over a squared minus blank over a cubed. 3 over blank plus blank over a squared minus blank over a cubed Last question of the day people, help me out please.

1. timo86m

its the same lol

2. timo86m

3/blank + blank/a^2 - blank/a^3

3. HayleyWhite17

Yeah cus I got myself confused with the other one

4. HayleyWhite17

Yessss

5. timo86m

silly goose

6. timo86m

you definately been thinking too much and hard :) but that is good, we at OS are proud of you :P

7. HayleyWhite17

So how do I solve this?

8. HayleyWhite17

Nevermind I'll just skip it and not get the points for it.

9. timo86m

10. timo86m

just treat blank as a variable and a as another variable

11. HayleyWhite17

No you have to replace the words "blank" with any variable then simplify it

12. timo86m

but blank is a variable :P

13. timo86m

ooh i'll make it simple you can choose a number so choose 1 :)

14. timo86m

you can use the same number 3 times i read 3/1 + 1/a^2 - 1/a^3

15. timo86m

(3*a^3+a-1)/a^3

16. HayleyWhite17

Is that what it simplifies to? :P

17. timo86m

yes :)

18. HayleyWhite17

How did you get that though so I can write it down!

20. HayleyWhite17

21. timo86m
