Her work is shown in the box below. Would Mrs. Tran get

the same result if she multiplied 5 × 4? Explain why or why not.

Yes, Mrs. Tran get the same result if she

multiplied 5 X 4,

Explanation:

Mrs. Tran worked as (3 X 4) + (2 X 4) = 12 + 8 = 20,

and Mrs. Tran got the same result if she multiply 5 X 4 = 20,

because in the equation both 3 and 2 are multiplied by 4,

So we add 3 and 2 first we get 5 and multiply by 4, So

the result remains same 20 for 5 X 4 also.
