Question

Which of the following expressions is modeled on the number line?

2 ⋅3
-2(3)
6 ÷ -3
0+6

Answer 1

Answer A: 2*3

Answer is A. First one
2 * 3 = 6
On the number line, 0 to 3, it's 3 units
then 3 to 6, there's another 3 units
so 2 x 3(units) = 6

Answer 2

The given line number suggests that there are 2 sets of 3 units.

Hence,

2 x 3 = 6 should be right answer.

Therefore, option (A) is true.

Explanation:

We can easily determine that on the line number:

• There are 3 units from 0 to 3.

• Then there are another 3 units from 3 to 6.

In other words, there are 2 sets of 3 units.

Hence,

2 x 3 = 6 should be right answer.

Therefore, option (A) is true.
