Aida applied the distributive property to write the equivalent expressions below.


15 + 21 = 3(4 + 8)


What is Aida’s error?


Aida used 3 as the factor, which is not common to 15 and 21.

Aida did not correctly divide by the common factor to get (4 + 8).

Aida did not apply the correct operations to the expressions.

Aida wrote two expressions that are not equivalent.

Answer:

Option B is the answer.

Step-by-step explanation:

Aida applied the distributive property to write the equivalent expressions given as

15 + 21 = 3(4 + 8)

But Aida made a mistake.

Since to get the common factor of 15 and 21 she did not divide these number of 3 correctly.

In simple words by division of 3 in 15 and 21 we get 5 and 7 instead of 5 and 8.

Therefore, option B is the correct answer.
