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

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

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

    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? \(\sf 8, 8.142857.~.~., 8.1414141414.~.~., 7.5\)

    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: \(\sf \dfrac{15}{2}, \sqrt{64}, 8.\overline{14}, 8 \dfrac{1}{7}\)
