The formula for calculating the proportion is: proportional value ÷ total value. The proportional formula is the proportional value/total value, and the pie chart is the best representation of the proportion, which is more intuitive than any formula. Proportion, that is, ratio, is the ratio of the quantity of different categories, that is, the value obtained by comparing two numbers. The 2D pie chart is circular, and compasses are often used in hand drawing. Only the data arranged in a column or a row of a worksheet can be drawn into a pie chart.

The difference between specific gravity and proportion

Proportion refers to a more or less proportion, and proportion is a specific percentage. In fact, the meanings of proportion and proportion are quite consistent, both of which refer to the meaning of proportion, but the proportion is general and accurate. For example, the proportion of our general employees in the Spring Festival benefits is not very high, and it is said that the proportion of managers is less than 30%.

The ratio is that the formula that two ratios are equal is called the ratio, and the four numbers that make up the ratio are called the proportional term. The two terms at both ends are called external terms of the ratio, and the two terms in the middle are called internal terms of the ratio. Proportion is also a common term in technical drawing, which refers to the ratio of the linear size of a figure in a drawing to its corresponding physical elements. In mathematics, proportion is the proportion of the number of parts in a population to the total, which is used to reflect the composition or structure of a population.
