The ratio of two ratio by the number two of the first ratio is not equal to the number of one of the latter ratio (or b not equal) to make them the same, then can write the ratio of the number of different amounts.
Ratio of two ratios The second number of the ratio is equal to the ratio of the latter (or b not equal) shall make such amount as before. Then can write the ratio of the number of them.
The ratio of the two ratios. The second number of not equal to the number of one of the first ratio ratio after (or B not rate) will have to make a number of such rate. Then can write ratio of several numbers.
