A ratio is a comparison of two numbers. We generally separate the two numbers in the ratio with a colon (:). Suppose we want to write the ratio of 8 and 12.
We can write this as 8:12 or as a fraction 8/12, and we say the ratio is eight to twelve while A proportion is an equation with a ratio on each side. It is a statement that two ratios are equal.
3/4 = 6/8 is an example of a proportion.
When one of the four numbers in a proportion is unknown, cross products may be used to find the unknown number. This is called solving the proportion. Question marks or letters are frequently used in place of the unknown number.

How does hydrazine and ammonia illustrate the law of multiple proportions?
Hydrazine (N2H4) and ammonia (NH3) illustrate the law of multiple proportions as they contain different proportions of nitrogen and hydrogen. Hydrazine has a 1:2 ratio of nitrogen to hydrogen atoms, while ammonia has a 1:3 ratio. This demonstrates that different compounds can be formed by combining the same elements in different proportions, as predicted by the law of multiple proportions.
