Compare Measurements: Is 40 mm Greater Than 5 cm?

To determine which measurement is larger, we'll convert the measurement in centimeters to millimeters to make a direct comparison:

• Step 1: Convert 5 centimeters to millimeters.

Using the conversion ratio, 1 cm = 10 mm, we find:

$5 \, \text{cm} \times 10 \, \frac{\text{mm}}{\text{cm}} = 50 \, \text{mm}$

• Step 2: Compare the two measurements.

Now we compare 40 mm and 50 mm:

$40 \, \text{mm}$ is less than $50 \, \text{mm}$.

Therefore, 40 mm is less than 5 cm when both are expressed in millimeters.

So the correct answer is:
