No, we generally say that ratio is a quantitative relationship, just like division and fraction, but division is an operation and fraction is a number, which is the difference between them. The ratio consists of two numbers, the first number is called the former item, the second number is called the latter item, and the middle is connected by ":",and the latter item cannot be 0. In the game, the score (the score is the result) is 3:0, which is pronounced as 3-0. Generally, the home team is in front (that is, the team playing at home), which means that the home team is now 3-0 ahead of the visiting team.
