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. The ratio can also be written in fractional form, such as 6/4, which is read as 6 to 4.

specific value

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. When making a comparison, it is read as one to three, and when making a score, it is read as one third.

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.
