The parsec is a unit of distance equivalent to about 3.26 light years or 31 trillion kilometres. It is used to measure the distances to stars, with kilo and mega parsecs being used for objects further away.
A parsec is based on the tangent ratio. The angle in question is that subtended at the distant object by the lines joining it to the earth and the sun, and the opposite side is the earth-sun distance - 1 astronomical unit (AU). The result is the distance of the object from the sun.

What operations are used to find equal ratios?
Multiplication and division.
Does a ratio have the same or different units?
It varies which means that it depends on what type of ratios are used
When two ratios are equal what are they called?
They are called equivalent ratios.
Why are all aspect ratios identified as something to 1 or perhaps even recorded as a decimal value?
It allows the ratios to be compared more easily. But they are NOT all defined as unit ratios. My monitor has an aspect ratios of 4:3 or 16:9.
How do complex fractions be used to solve problems involving ratios?
you can use it by writing out the complex into a division problem then improper fraction
What fields of study use ratios?
Ratios are used in biology, astronomy and math. Most every science where comparisons are made (and that is just about every science) requires a good understanding of ratios. They are particularly important in medicine, in mixing dosages.

How do the ratios of side lenghts compare for triangles that are not similar?
There are no ratios that can be used for triangles that are not similar.
How to create equivalent ratios?
Ratios are used to compare numbers. When you're working with ratios, it's sometimes easier to work with an equivalent ratio.
What was astrolabes and quadrants used for?
Astronomy...
Is neon used in astronomy?
Neon is a substance considered in astronomy because there are small traces of it in the sun.
What do astronomical mean?
It means "related to Astronomy".Also, since some very large numbers are used in Astronomy, especially for distances, "astronomical" is also used (in popular speech) in the sense of "huge, enormous".It means "related to Astronomy".Also, since some very large numbers are used in Astronomy, especially for distances, "astronomical" is also used (in popular speech) in the sense of "huge, enormous".It means "related to Astronomy".Also, since some very large numbers are used in Astronomy, especially for distances, "astronomical" is also used (in popular speech) in the sense of "huge, enormous".It means "related to Astronomy".Also, since some very large numbers are used in Astronomy, especially for distances, "astronomical" is also used (in popular speech) in the sense of "huge, enormous".
