The first person to recognize the total ratio of the number atoms is the same as the total ratio of the ratio of the mass is JOHN DALTON.This is also called the "Law of Multiple Proportion"
number of deaths by total number of deaths in a population
To calculate the ratio of purines to pyrimidines in a nucleic acid sequence, count the number of purine bases (adenine and guanine) and the number of pyrimidine bases (thymine, cytosine, and uracil) in the sequence. Then divide the total number of purines by the total number of pyrimidines to get the ratio.
Add them together!
The answer to this question depends on the ratio os what aspect of plants and humans you are interested in. Is it the ratio of:the number of speciesthe number of individualsthe total (bio-)mass.
experimental probability
the ratio of the number favorable outcomes to the total number of trials.
The ratio of Italian hoagies sold to the total number of hoagies sold is X:Y, where X represents the number of Italian hoagies sold and Y represents the total number of hoagies sold.
number of boys = ratio of boys x total strength / total ratio = 5 x 27/9 = 5 x 3 = 15 number of girls = ratio of girls x total strength / total ratio = 4 x 27/9 = 4 x 3 = 12 verification: 15 + 12 = 27
If each of the ways is equally likely then it is the probability of the event but otherwise it is simply a ratio.
The probability of the event occurring.
You find the total number of outcomes by adding the first part of the odds to the second part of the odds. For example: 1:1 The total number of outcomes would be 2. To find the ratio of equally likely outcomes to the total number, find the number of outcomes, and put it on the left of the semicolon. Then put the total number on the right side. For the same example: (outcomes)->1:2<-(total)
