Question

Paolo is using number lines to find the value of the expression
1/6+ 2/3+ (-1 1/3).His first two steps are shown.

A. Draw an arrow on the number line provided to show the last step.


Step 1: Start at 1/6.


Step 2: Add 2/3.

Last step: Add (- 1 1/3)


B. What is the value of the expression 1/6+ 2/3+ (-1 1/3)?

Answer 1

$\frac{1}{6} + \frac{2}{3} + (-1 \frac{1}{3} )$

$\frac{1}{6} + \frac{4}{6} + ( - \frac{4}{3} )$

$\frac{5}{6} - \frac{8}{6}$

$\frac{ - 3}{6}$

$- \frac{1}{2}$
