Comparison is a division formula consisting of the former item and the latter item, except that "∫" (division symbol) is changed to ":"(comparison symbol), but the division formula represents an operation, and the ratio represents the relationship between two numbers. A fractional line similar to a fraction.

For example, for example, 6÷4 writes 6:4 as a ratio. ":"is a comparative symbol, pronounced "than". The number before the comparison symbol is called the first item of comparison, and the number after the comparison symbol is called the last item of comparison. In this example, 6 is the first term of this ratio and 4 is the last term of this ratio.

I. Ratio

The number obtained by dividing the former term by the latter term is called the ratio. This ratio can be expressed in fractions, decimals or integers.

For example, the ratio of1:3 =1÷ 3 =1/3; 1/3 is also a way of writing, which is read as one-to-three comparison and one-third score.

Two ratios with equal ratios can form a ratio, which is connected by an = sign. When the denominator in the ratio is 1, it can be written as an integer.

For example: 50:25=2 or 2/ 1 or 2.

Second, the basic nature

1, the first term and the last term of the ratio are multiplied or divided by the same number at the same time (except 0), and the ratio remains unchanged.

2. The first term and the last term of the simplest ratio are mutually qualitative, and the first term and the last term of the ratio are integers.

3. The ratio is usually expressed as an integer, and can also be expressed as a fraction or decimal.

4. The last item of the ratio cannot be 0.

5. The last term of the ratio is multiplied by the first term of the ratio.
