  1. Evaluate the following.

    1. \(\left| {-767} \right| \)

      \(\left| {-767} \right| = 767\)

    2. \(\left| {51} \right| \)

      \(\left| {51} \right| = 51\)


  2. Write the following numbers in order from least to greatest.

    \[\left| 3.5 \right|, \thinspace \left| {-5} \right|, \thinspace -\frac{3}{2}, \thinspace \left| 7 \right|, \thinspace -\left| {12} \right|, \thinspace \left| {\frac{{13}}{2}} \right|, \thinspace 16 \]
    Start by evaluating each number in decimals, where appropriate.
    \(3.5\), \(5\), \(-1.5\), \(7\), \(-12\), \(6.5\), \(16\)

    Now, arrange the decimal numbers from least to greatest.
    \(-12\), \(-1.5\), \(3.5\), \(5\), \(6.5\), \(7\), \(16\)

    Then, arrange the original numbers from least to greatest.
    \[-\left| 12 \right|, \thinspace -\frac{3}{2}, \thinspace \left| 3.5 \right|, \thinspace \left| -5 \right|, \thinspace \left| \frac{13}{2} \right|, \thinspace \left| 7 \right|, \thinspace 16\]
