Hence,
Therefore, a milligram is
c.
To calculate: Which is greater, 10,000 milligrams or 1000 decigrams? Explain your reasoning.
Unit of mass | Kilogram | hectogram | dekagram | decigram | Centigram | milligram | microgram | nanogram |
Mass (in grams) |
c.
Answer to Problem 17Q
1000 decigram is greater than 10,000 milligram.
Explanation of Solution
Given information: Use table for the values
Calculation: Both units are different so we cannot compare them, so convert both units into grams
Converting milligram to gram
Multiplying above equation both sides by 10,000, we get
Converting decigram to gram
Multiplying above equation both sides by 1,000, we get
Hence, 1000 decigram is greater than 10,000 milligram because 100 gram is greater than 10 grams
