Division is a method of mathematics which helps to find the outcomes of after separating one whole piece or number into various small parts. In other words it is the process of separation of any object or number into small divisible units.
In the given question, the spaghetti is being folded once and then chopped [tex]20\; times[/tex].
Calculation
We know that if we separate one straight spaghetti for the given number of times we will get [tex]21 parts[/tex] of spaghetti.
By folding the spaghetti once before placing a cut on it, the number of parts will be affected but not exactly in the same proportion because the folding part of spaghetti will not get separated by placing the cuts.
[tex]\begin{aligned}\rm\:pieces\: of\: spaghetti&=(21\: sets \times 2)-1\\\rm\:pieces\:of\:spaghetti&=42-1\\\rm\:pieces\: of\: spaghetti&=41 \:pieces\end[/tex]
Elaborating further, placing 20 cuts on folded spaghetti will divide it into 21 sets of two pieces but the last part is a joint of spaghetti, and it will not get separated into two parts. Hence the last part will be counted as 1 separate piece instead of two pieces of spaghetti.
Therefore the outcome will be [tex]41\:pieces\\[/tex] of spaghetti by placing cuts on a folded spaghetti twenty times.
