Question

Fred wants to separate 4 X 4 array into a 2 X4 array and a 3 X 4 array.Can Fred do this? Explain.3rd grade subject

Answer 1

Answer:

No

Explanation:

Given two arrays: 2 x 4 and 3 x 4

Combining these two arrays will give:

$(2\times4)+(3\times4)=(2+3)\times4=5\times4$

A combination will give a (5 x 4) array as shown above.

Therefore, Fred cannot separate a (4 x 4) array into a 2 X4 array and a 3 X 4 array.
