What model can you use to represent −14÷−7
?(1 point)
The model that can be used to represent −14÷−7 is a number line.
To represent the division −14 ÷ −7, we can use the following model:
- Start with a horizontal number line.
- Place a dot at 0.
- Move 14 units to the left from 0 and place another dot.
- Then, split the number line into 7 equal parts.
- Each part represents one unit.
- Since we are dividing by −7, we move in the opposite direction to the left.
- Count how many groups of 7 we can fit in the 14 units.
- We can fit 2 groups of 7 units.
- Therefore, the model represents −14 ÷ −7 as −2.
