Can u order 4/9 444/1000 .4 from least to greatest
quester [9]
.4 is the smallest since 4/10 is smaller than 4/9 and is only worth 400/1000.

4/9 is a repeater  .444.... with the fours continuing forever.  If we just go out 3 places from the decimal we get .444 which is 444/1000 and is the second number.  Because the 4's continue to go on forever this makes it larger than 444/1000

So the correct order least to greatest is .4 < 444/1000< 4/9

17/3 (x - 3/2) = - 5/4 <br> can you solve for x?
kow [346]

Answer:

\boxed{x =\dfrac{87}{68}}

Step-by-step explanation:

\dfrac{17}{3} \left(x-\dfrac{3}{2} \right) = -\dfrac{5}{4}

Using FOIL in LHS

\dfrac{17}{3}x - \dfrac{17}{3} \cdot \dfrac{3}{2} = -\dfrac{5}{4}

\dfrac{17}{3}x - \dfrac{51}{6} = -\dfrac{5}{4}

\dfrac{17}{3}x = -\dfrac{5}{4}+ \dfrac{51}{6}

\dfrac{17}{3}x = -\dfrac{5(3)}{4(3)}+ \dfrac{51(2)}{6(2)}

\dfrac{17}{3}x = -\dfrac{15}{12}+ \dfrac{102}{12}

Now the denominator of the fractions in the RHS are the same

\dfrac{17}{3}x = \dfrac{87}{12}

x = \dfrac{87}{12} \cdot \dfrac{3}{17}

x =\dfrac{261}{204} = \dfrac{87}{68}

\boxed{x =\dfrac{87}{68}}
