Question

Zelda completed the right column of the table to help her find the difference.

Answer 1

Answer:

His error occurred in the last step

Explanation:

He was supposed to calculate -

$\frac{5}{6} - \frac{1}{9} \\or\\\frac{15}{18} - \frac{2}{18}$

which would equal -

$\frac{13}{18} \\not\\\frac{17}{18}$

Because he added instead of subtracted.

Hope this helps!
