4 (21+10)

Sari’s error is that she did not use the greatest common factor in the equation. Option D is correct.

What is the greatest common factor?

The biggest common factor is the greatest of the common factors among the quantities presented, as the name suggests.

Factors of 84: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84

Factors of 40: 1, 2, 4, 5, 8, 10, 20, 40

The given expression;

84 + 40 = 2 (42 + 20)

From the above, the greatest common factor for the numbers will be 4. Which is represented as;

84 + 40 = 4 (21 + 10)

Sari’s error is that she did not use the greatest common factor in the equation.

Hence, option D is correct.
