Final answer:
Meters as a unit of length cannot be compared directly to kilograms as a unit of mass. For direct comparison, two measurements must describe the same type of quantity, such as both being units of length or mass. correct answer is D.
Step-by-step explanation:
The question, 'Is 4 meters greater or less than 160 kilograms?' cannot be directly compared because they are units of different quantities. Meters are a measure of length in the metric system, while kilograms are a measure of mass. To compare two measurements, they must describe the same type of quantity. To give a sense of differences in the same units, you would convert each to comparable units, such as comparing lengths in meters or weights in kilograms, but length cannot be compared to mass directly.
For example, in comparing distances, you can convert meters to kilometers by understanding that 1000 meters equal 1 kilometer. So, 400 meters would be 0.4 kilometers, which is less than 2 kilometers. Similarly, if you have measurements in millimeters and centimeters, you would convert them to the same units before comparing: 45 centimeters is less than 500 millimeters because there are 10 millimeters in a centimeter. When converting to meters, 200 centimeters equals 2 meters, so Juliana can measure 200 cm with a meter stick. In cases of weight, it's important to use the same units to compare weights in grams and kilograms by understanding the conversion factors within the metric system.
