Compare Units: Is 40 Meters Greater Than 0.04 Kilometers?

Q: Why can't I just compare the numbers 40 and 0.04?

You can't compare numbers with different units! It's like comparing 40 apples to 0.04 bags of apples - you need to know how many apples are in each bag first.

Q: How do I remember the conversion factor?

Remember: kilo means 1000, so 1 kilometer = 1000 meters. Think of it like 1 kilogram = 1000 grams - same prefix pattern!

Q: What if I get confused about which direction to convert?

Use this trick: meters are smaller units, so you need more of them to equal the same distance. 1 km should equal a big number of meters (1000).

Q: Are there other metric conversions I should know?

Understand the problem

Which is larger?

40 meters ⬜ 0.04 km

Step-by-step solution

To solve this problem, we need to compare two distances: 40 meters and 0.04 kilometers.

Let's follow these steps to reach the solution:

Step 1: Convert 0.04 kilometers to meters.
Step 2: Compare the converted distance with 40 meters.

Now, we'll work each step in detail:

Step 1: Convert 0.04 kilometers to meters.

The conversion factor is $1 \text{ km} = 1000 \text{ meters}$ .

Thus, $0.04 \text{ km} \times 1000 = 40 \text{ meters}$ .

Step 2: Compare the two distances:

We have both distances as 40 meters now. Therefore, 40 meters is equal to 40 meters.

The solution is that the two distances are equal, so the comparison operator is:

$=$

Key Points to Remember

Essential concepts to master this topic

Conversion: Use 1 km = 1000 meters for all comparisons
Technique: Convert 0.04 km × 1000 = 40 meters
Check: Both values in same units: 40 m = 40 m ✓

Common Mistakes

Avoid these frequent errors

Comparing values in different units
Don't compare 40 meters to 0.04 km directly = wrong comparison! This gives false results because you're mixing units. Always convert both measurements to the same unit before comparing.
