How do you convert three numbers into a ratio?
One way to do it is to look at each of the three as a part of the total. So you can consider the ratio 2:3:7 as the first thing being 2/12 of the total, the second being 3/12 and the third being 7/12.
How to convert inches into a percentage?
Inches are a measurement of distance and are part of a group known as scaler quantities (i.e. those that have magnitude only). However percentages are a form of ratio expressed as a fraction of 100.In order to convert inches into a percentage, you need a minimum of two values or measurements to compare to each other (to form the ratio).For example if one man (Dave) is 72 inches tall and another man (John) is 78 inches tall then what percentage of John's height is Dave?To find the answer we divide Dave's height by John's and then multiply by 100.(72/78) x 100 = 92.3 %So Dave's height is 92.3 % of John's height.
How do you covert percentages to mixed numbers?
Divide the percentage number by 100 to convert it to a fraction. If the answer consists of an integer part and a fractional part then you will have a mixed number.

What does a higher dependency ratio mean?
In demography, a dependency ratio is usually the ratio of the non-productive members of the population to the productive members. This is because the econmic well-being of the whole population - the productive and non-productive members - depends on the value produced by the productive part. The non-productive population comprises the youngsters (aged up to 15), and the older people (aged 65 and over) while the productive part is the population aged 15 to 64. The ratio is usually expressed as a percentage. A high ratio means that each working person is, effectively supporting, more people.
How do you explain ratio?
a ratio is a comparison between 2 or more things. To work ratio out, it will be easier if you separate it into parts. if you was to work out the ratio of money, you would add the ratio together. whatever the number is you convert into money. you would then times it by the first number of the ratio which is the answer of the first of the first part, then you add it to the second number, and then that is the answer to the ratio problem. This is an example: if you had to work out £100 and the ratio was 8:2 this is how you would do it. first part you add the 8 and the 2 together which is 10, convert that into money it is £10 second part you times the 8 and the £10 together which is £80 third part you times the 2 and the £10 together which is £20 then you put it in ratio which is £80:£20

Is percentage a unit?
Yes. percentage is a unit for a ratio. 100% ( 100 percent ) equals the normalized form of a ratio of 1/1 (one to one) which is 1.0. 50% ( 50 percent ) equals the normalized form of a ratio of 1/2 (one to two) which is 0.5. Scaling a value by a normalized ratio can be archived by simple multiplication. 22 * 0.5 Scaling a value by a percentage value can be archived by normalizing the percentage value first by divion by 100: percentage value / 100 = normalized value 50 / 100 = 0.5 other units for a ratio are: Per mille (‰) 1 part in 1,000 Basis point (‱) 1 part in 10,000 Per cent mille (pcm) 1 part in 100,000 Parts-per notation Concentration Grade (slope)

How do yo do ratio maths?
To share in a given ratio 1) Simplyfy the given ratio by putting each part of the ratio over the LCD 2) find the total no. of parts (add up the simplified ratio) 3) no. of parts / total no. of parts x total amount to be shared = the amout each person reacieves
What is a ratio that compares a part of the whole to another part of the whole?
A Part-to-part ratio
Why does order matter in ratios?
The order of a ratio only matters as far as the "title" or "description" of the ratio. A bottle of squash may say "dilute this in the ratio of 1:5 with water". This would formally be stated as "the ratio of squash to water is 1:5", ie for every 1 part of squash there is, there should be 5 parts of water. Each part of the ratio refers to a specific part of the description: the first part of the ratio (in this case "1") refers to the first part of the description (in this case "squash") and the second part of the ratio ("5") refers to the second part of the description ("water"). If the ratio is reversed WITHOUT reversing the "titles", it becomes the ratio of squash to water is 5:1 meaning for every 5 parts squash there is only 1 part water - a very concentrated drink that will not be very nice to drink (nor very healthy for the teeth) - which is not the same. However, reversing the "title" of the ratio as well as the ratio itself is perfectly acceptable as each part of the ratio still refers to the same thing: above would be come the ratio of water to squash is 5:1 meaning that for every 5 parts of water there is 1 part of squash - the "5" still refers to "water" and the "1" still refers to "squash".

The ratio of the angle measures in a triangle is 1 to 6 to 13. What is the measure of each angle?
In this instance, each "part" of the ratio is divided into 20. There is a total of 180 degrees in the three internal angles of a triangle, therefore each "part" of the ratio is equal to nine degrees.Therefore, in this instance, if the angles are in the ratio 1:6:13, the angles themselves are 1 x 9 = 9 degrees, 6 x 9 = 54 degrees, and 13 x 9 = 117 degrees.
