Question

Match the following prefixes with their multiples

Prefixes	Multiples
1. Micro	\[{10^6}\]
2. Deca	\[{10^9}\]
3. Mega	\[{10^{ - 6}}\]
4. Giga	\[{10^{ - 15}}\]
5. Femto	\[{10^{}}\]

Answer 1

Hint: To solve this we need to know about the metric prefixes. These have their special symbols and each have different values and connected to each other by some multiples. Some of them are S.I units also which are used prevalently.

Complete step by step answer:
Metric prefixes are the unit prefixes used to denote or indicate the multiples or sub-multiples of the unit. Every prefix has a unique symbol. There are a handful of Standard prefixes which are standardized by the International Bureau Of Weights And Measures .
Some of them are:

Prefixes	Symbols	Multiples
1. Peta	P	\[{10^{15}}\]
2. Tera	T	\[{10^{12}}\]
3. Giga	G	\[{10^9}\]
4.Mega	M	\[{10^6}\]
5. Kilo	K	\[{10^3}\]
6. Hecto	h	\[{10^2}\]
7. Deca	da	\[{10^1}\]
\[{10^0}\] \[1\]
8. Deci	d	\[{10^{ - 1}}\]
9. Centi	c	\[{10^{ - 2}}\]
10. Mili	m	\[{10^{ - 3}}\]
11. Micro	\[\mu \]
12. Nano	n	\[{10^{ - 9}}\]
13. Pico	p	\[{10^{ - 12}}\]
14. Femto	f	\[{10^{ - 15}}\]

So, on referring to the above table we can see many prefixes and symbols as well as their multiples.
Now we can match the table very comfortably.
So, the correct matching is:

Prefixes	Multiples
1. Micro	\[{10^{ - 6}}\]
2. Deca	\[{10^1}or10\]
3. Mega	\[{10^6}\]
4. Giga	\[{10^9}\]
5. Femto	\[{10^{ - 15}}\]

Note: Additional information: Metric units are used in mass as kilograms, decagrams etc, in volume as cubic centimeter, cubic kilometer etc, in length as kilometer, centimeter, nanometer etc, in time as nanoseconds, microseconds etc and many more units also.
One should remember the names associated with the multiple because in question only names are mentioned and we are expected to know the multiple which are very important for conversions in any type of numerical. If we substitute the wrong multiple for a prefix it can totally alter our answer with a large difference.
