Working out:

In the fourth line of the multiplication the author might have said 2 $1/undefined$ $1/undefined$, and then the last line would have been 1 $1/undefined$ $1/undefined$, and he uses this form, in giving his answer above, for the part that $1/undefined$ of 17 makes towards 2. Somewhat similarly in the case of 23 he changes 1 $1/undefined$ $1/undefined$ $1/undefined$ to 1 $1/undefined$ $1/undefined$.
