Just divide the larger number by the smaller number and report and the answer as 1: something. Example: Suppose you want the ratio of 750 to 225. So write it as 750:225 ::x:1.

To write a percentage as an odds ratio, convert the percentage to a decimal x, then calculate as follows: (1/x) - 1 = first number in the odds ratio, while the second number in the odds ratio is 1.

A ratio is a fraction which compares two quantities. ... In two similar geometric figures, the ratio of their corresponding sides is called the scale factor. To find the scale factor, locate two corresponding sides, one on each figure.

To calculate the ratio for each screen, the formula will divide the width by the height, and format the result as a fraction. Then, the slash will be replaced with a colon, to create the ratio.

A ratio is a comparison between two quantities or numbers. Ratios can be written in fraction form, with a colon or by using the word “to”. A proportion is created when two ratios are equal, or we can say that two equal ratios form a proportion. ...

Calculating the ratio of two numbers is just as easy as to divide the two numbers. For example, if I wanted a 16:9 ratio, I would divide 16 by 9.

To calculate the molar ratios, you put the moles of one reactant over the moles of the other reactant. Usually, you divide each number in the fraction by the smaller number of moles. This gives a ratio in which no number is less than 1.

To calculate your cholesterol ratio, divide your total cholesterol number by your HDL cholesterol number. So if your total cholesterol is 200 mg/dL (5.2 mmol/L) and your HDL is 50 mg/dL (1.3 mmol/L), your ratio would be 4-to-1. Higher ratios mean a higher risk of heart disease.

If you have a random pair of numbers and you want to know the delta – or difference – between them, just subtract the smaller one from the larger one. For example, the delta between 3 and 6 is (6 - 3) = 3. If one of the numbers is negative, add the two numbers together.

A ratio is a way to compare two quantities by using division as in miles per hour where we compare miles and hours. A proportion on the other hand is an equation that says that two ratios are equivalent. ... If one number in a proportion is unknown you can find that number by solving the proportion.

To find it, we use the percent proportion (or we can set up an equation as we did last time). A B = r 100 where A is the amount, B is the base, and r is the rate (without the % sign. i.e. if R = 25%, then we just use r = 25.)

By multiplying each ratio by the second number of the other ratio, you can determine if they are equivalent. Multiply both numbers in the first ratio by the second number of the second ratio. For example, if the ratios are 3:5 and 9:15, multiply 3 by 15 and 5 by 15 to get 45:75.

Subtract the minimum from the maximum. This is the range. In the example, 500,000 minus 350,000 equals 150,000. Divide the range by the minimum to find the range spread.
