Question

Choose the correct addition statement that calculates the number of oranges packed for the given bar model.

• A. 100 = 40 + 60
• B. 40 = 60 + 20
• C. 20 + 40 = 60
• D. 40 – 20 = 60

Answer 1

The correct option is C 20 + 40 = 60

Given information in the bar model:
$\bullet$ Total number of oranges = 60
$\bullet$ Number of packed oranges = ?
$\bullet$ Number of unpacked oranges = 40



We know that in a bar model:
Part 1 + Part 2 = Whole

So, the correct addition statement for this bar model will be: ? + 40 = 60
To solve this statement, we can subtract 40 from 60. And we will get 20 as the answer.
So, the correct addition statement for this bar model will be: 20 + 40 = 60
