Question

Which of the following options shows the correct answer to the given problem?

• A.
• B.
• C.
• D.

Answer 1

The correct option is D

Say:
On our screen, we have a picture that shows the addition of numbers using the bars and cubes model.

Steps:

• The first number is: 5 Tens and 4 Ones = 50 + 4 = 54.
• The second number is: 3 Tens and 8 Ones = 30 + 8 = 38.
• Thus, when we’ll add them: 50 + 30 + 4 + 8 = 80 + 12.
• 12 has 1 Ten and 2 Ones.
• Therefore, we can write: 80 + 10 + 2 = 90 + 2 = 92. Hence, option D is correct.
