Final answer:
To determine if one value is greater than another, convert both values to the same unit and compare them. For example, 1000 mm is greater than 20 cm once converted to the same unit (100 cm is greater than 20 cm).
Step-by-step explanation:
To check if value1 is greater than value2, you should first ensure that both values are in the same units. For instance, if you are comparing lengths in millimeters and centimeters, you need to convert them to the same unit. Let's take 1000 mm and 20 cm as an example.
Next, convert mm to cm by understanding that 10 mm is equivalent to 1 cm. Therefore, 1000 mm divided by 10 equals 100 cm. Now that both lengths are in the same unit, you can compare them directly.
Then, compare the two measurements. It is clear that 100 cm is greater than 20 cm. So, the answer to whether 1000 mm is greater than 20 cm is affirmative: 1000 mm is indeed larger than 20 cm.
