A ratio is a comparison of two numbers. You can write a ratio in these ways:
a to b, a : b, or a/b. Ratios are often written as fractions. A ratio that is expressed as a fraction is generally written in lowest terms. If the ratio involves unit of measure, you must ensure that the units are the same.
Example:
Write ratios in lowest terms.
20/52 = (20/4)/(52/4) = 5/13
240/200 = (240/40)/(200/40) = 6/5
There are continued ratio, or extended ratio, which relates more than two numbers.
Example:
The measures of the angles of a triangle are related by the ratio 3 : 4 : 5. Find the measure of each angle.
Solution:
The ratio 3 : 4 : 5 is equivalent to 3x + 4x + 5x. We write an equation by using, 3x, 4x, and 5x to represent the measures of the angles. The sum of the angles of a triangle is 180 degrees. So,
3x + 4x + 5x = 180
12x = 180
x = 15
Thus, the measures of the angles are 45 degrees, 60 degrees, and 75 degrees.

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.
What is the Equivalent ratios for 3 to 3 12?
yes
An equation that states that two ratios are equal?
An equation that states that two ratios are equal is a proportion.
What is true about ratios for proportional relationships that is not true about ratios for other relationships?
For proportional relationships the ratio is a constant.
Are all ratios a fraction?
All ratios can be written as fractions.
Is it true an ionic compound is written by using the highest ratios of the ions in the compound?
No. It is written using the lowest ratios. Writing with the highest ratios would be impossible.
Can ratios be written any way?
hg
Can Some fractions and ratios can be written as mixed numbers?
fractions can't be written as a mixed number because it's already a fraction but im not sure about ratios.
An ionic compound is written by using the highest ratios of the ions in a compound?
An ionic compound is written by using the lowest ratios of the ions in a compound. E.g. magnesium chloride is not Mg6Cl12, but MgCl2.

What ia an comparison of numbers or variables that can be written in fraction form?
They are ratios.
What is a comparison of numbers or variables that can be written as a fraction form?
They are known as ratios.
How do you express ratios in the form 1 to n?
Ratios can be written either like this 4/5 or 4:5 both mean 4 out of 5
How are ratios written?
normally with a colon ":"so a ratio of 1 to 50 would be written 1:50
