Solve It! Reasoning: Explain why you cannot cut them into congruent pieces, each with size 4/5.

You cannot cut the three 1-squares into congruent 4/5-pieces because 3 ÷ 4/5 is not a whole number.

You cannot cut the three 1-squares into congruent 4/5-pieces because 3 × 4/5 is not a whole number.

You cannot cut the three 1-squares into congruent 4/5-pieces because 3 is an odd number.
