in each pair of prefixes, circle the prefix that is smaller.

1. micro or milli 17. kilo or deca 18. centi or deci
2. mega or terra 20. hecto or nano

what is each of the following measuring? (volume, length or mass )

1. terragram 22. kiloliter
2. nanometer 24. megameter
3. deciliter 26. decagram
4. centigram 28. hectometer

Explanation:

1. GL: "Giga" is a prefix meaning \(10^{9}\), and "L" stands for liter (a unit of volume). So, GL means gigaliter.
2. Hm: "Hecto" is a prefix (\(10^{2}\)), and "m" stands for meter (a unit of length). So, Hm means hectometer.
3. mm: "Milli" is a prefix (\(10^{- 3}\)), and "m" stands for meter. So, mm means millimeter.
4. Mm: "Mega" is a prefix (\(10^{6}\)), and "m" stands for meter. So, Mm means megameter.
5. dg: "Deci" is a prefix (\(10^{-1}\)), and "g" stands for gram (a unit of mass). So, dg means decigram.
6. μg: "Micro" is a prefix (\(10^{-6}\)), and "g" stands for gram. So, μg means microgram.
7. cL: "Centi" is a prefix (\(10^{-2}\)), and "L" stands for liter. So, cL means centiliter.
8. m: "m" stands for meter (a unit of length).
9. TL: "Tera" is a prefix (\(10^{12}\)), and "L" stands for liter. So, TL means teraliter.
10. DL: "Deci" is a prefix (\(10^{-1}\)), and "L" stands for liter. So, DL means deciliter.
11. deca: "Deci" (\(10^{-1}\)) vs. "deca" (\(10^{1}\)). Since \(10^{1}>10^{-1}\), deca is larger.
12. kilo: "Kilo" (\(10^{3}\)) vs. "hecto" (\(10^{2}\)). Since \(10^{3}>10^{2}\), kilo is larger.
13. micro: "Nano" (\(10^{-9}\)) vs. "micro" (\(10^{-6}\)). Since \(10^{-6}>10^{-9}\), micro is larger.
14. centi: "Milli" (\(10^{-3}\)) vs. "centi" (\(10^{-2}\)). Since \(10^{-2}>10^{-3}\), centi is larger.
15. giga: "Giga" (\(10^{9}\)) vs. "mega" (\(10^{6}\)). Since \(10^{9}>10^{6}\), giga is larger.
16. micro: "Micro" (\(10^{-6}\)) vs. "milli" (\(10^{-3}\)). Since \(10^{-6}<10^{-3}\), micro is smaller.
17. deca: "Kilo" (\(10^{3}\)) vs. "deca" (\(10^{1}\)). Since \(10^{1}<10^{3}\), deca is smaller.
18. centi: "Centi" (\(10^{-2}\)) vs. "deci" (\(10^{-1}\)). Since \(10^{-2}<10^{-1}\), centi is smaller.
19. mega: "Mega" (\(10^{6}\)) vs. "terra" (\(10^{12}\)). Since \(10^{6}<10^{12}\), mega is smaller.
20. nano: "Hecto" (\(10^{2}\)) vs. "nano" (\(10^{-9}\)). Since \(10^{-9}<10^{2}\), nano is smaller.
21. mass: "Gram" is a unit of mass, and "terra" is a prefix. So, terragram is a unit of mass.
22. volume: "Liter" is a unit of volume, and "kilo" is a prefix. So, kiloliter is a unit of volume.
23. length: "Meter" is a unit of length, and "nano" is a prefix. So, nanometer is a unit of length.
24. length: "Meter" is a unit of length, and "mega" is a prefix. So, megameter is a unit of length.
25. volume: "Liter" is a unit of volume, and "deci" is a prefix. So, deciliter is a unit of volume.
26. mass: "Gram" is a unit of mass, and "deca" is a prefix. So, decagram is a unit of mass.
27. mass: "Gram" is a unit of mass, and "centi" is a prefix. So, centigram is a unit of mass.
28. length: "Meter" is a unit of length, and "hecto" is a prefix. So, hectometer is a unit of length.
