For Question #3, simplify all the fractions into decimals. \(\sf \dfrac{42}{999}, \dfrac{42}{999}, \dfrac{42}{99}, \dfrac{99}{42}\)
iGreen
  • iGreen
Plug them into your calculator..tell me what you get for each one.
iGreen
  • iGreen
We're looking for the one that looks like \(\sf 0.424242424242.~.~.\)

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

42/99 = ?
anonymous

0.424242424242
iGreen
  • iGreen
Yes, so which one is correct?
anonymous
  • anonymous
42/99
iGreen

ok im working on 4

Okay, convert all of them to decimals.

\(\sf \sqrt{64}=~\! ?\) \(\sf 8 \dfrac{1}{7} = ~ \! ?\) \(\sf 8.\overline{14} = ~ \! ?\) \(\sf \dfrac{15}{2} = ~ \! ?\)
iGreen
  • iGreen
Do the first one, tell me what you get.

64=8 8 1/7=0.142857 8.14=0.57142857 15/2=7.5
iGreen
  • 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? \(\sf 8, 8.142857.~.~., 8.1414141414.~.~., 7.5\)
iGreen

I gotta go soon..
anonymous
  • anonymous
so what does that mean
iGreen
  • iGreen
Which number is the smallest out of those?
anonymous
  • anonymous
15/2
iGreen
  • iGreen
Yes, then which one is the next smallest?
anonymous
  • anonymous
64
iGreen
  • iGreen
Correct..then which one? So far we have: \(\sf \dfrac{15}{2}, \sqrt{64}\)
iGreen
  • 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: \(\sf \dfrac{15}{2}, \sqrt{64}, 8.\overline{14}, 8 \dfrac{1}{7}\)
