Answer:

25 is the least number of moves required to join all 50 pieces.

Step-by-step explanation:

Given : A jigsaw puzzle contains 50 pieces. If joining any two pieces is considered one move.

To find : What is the least number of moves required to join all 50 pieces?

Solution :

Total number of pieces in a jigsaw puzzle = 50

If joining any two pieces is considered one move.

Which means, 1 piece = $\frac{1}{2}$ move.

So, to find least number of moves required to join all 50 pieces is
