Okay, which question are you having trouble on?

3. anonymous

im trying to find out what is wrong and what is right

4. iGreen

For Question #3, simplify all the fractions into decimals. $$\sf \dfrac{42}{999}, \dfrac{42}{999}, \dfrac{42}{99}, \dfrac{99}{42}$$

5. iGreen

Plug them into your calculator..tell me what you get for each one.

6. iGreen

We're looking for the one that looks like $$\sf 0.424242424242.~.~.$$

7. anonymous

42/999=0.04204204 42/999=0.04204204 42/99=

8. iGreen

42/99 = ?

9. anonymous

0.424242424242

10. iGreen

Yes, so which one is correct?

11. anonymous

42/99

12. iGreen

Yes, and which option has that?

13. anonymous

b

14. anonymous

c

15. iGreen

Yes, C is correct.

16. anonymous

ok im working on 4

17. iGreen

Okay, convert all of them to decimals.

18. iGreen

$$\sf \sqrt{64}=~\! ?$$ $$\sf 8 \dfrac{1}{7} = ~ \! ?$$ $$\sf 8.\overline{14} = ~ \! ?$$ $$\sf \dfrac{15}{2} = ~ \! ?$$

19. iGreen

Do the first one, tell me what you get.

20. anonymous

64=8 8 1/7=0.142857 8.14=0.57142857 15/2=7.5

21. iGreen

Not quite. $$\sf 8 \dfrac{1}{7} = 8.142857.~.~.$$ You got the $$\sf \dfrac{1}{7}$$ part correct, but don't forget to add $$\sf 8$$. Also, the overline sign means that those two numbers repeat. $$\sf 8.\overline{14} = 8.1414141414.~.~.$$ So can you arrange these from least to greatest? $$\sf 8, 8.142857.~.~., 8.1414141414.~.~., 7.5$$

22. iGreen

I gotta go soon..

23. anonymous

so what does that mean

24. iGreen

Which number is the smallest out of those?

25. anonymous

15/2

26. iGreen

Yes, then which one is the next smallest?

27. anonymous

64

28. iGreen

Correct..then which one? So far we have: $$\sf \dfrac{15}{2}, \sqrt{64}$$

29. iGreen

It should be $$\sf 8.\overline{14}$$ 8.14141 8.14285 8.14 is the same for both, compare the next number. The first one has 1, and the second has 2, therefore the 2nd is bigger than the first. 8.14285 > 8.14141 So: $$\sf 8 \dfrac{1}{7} > 8.\overline{14}$$ So our final answer is: $$\sf \dfrac{15}{2}, \sqrt{64}, 8.\overline{14}, 8 \dfrac{1}{7}$$

30. iGreen

I have to go..bye
