How to read the math score of the second day of junior high school
The number of reading components in the math score of the second day of junior high school. A/B formula (A and B are algebraic expressions, and B contains letters) is called a fraction. Where a is called the numerator of the fraction and b is called the denominator of the fraction.

When the numerator of a fraction is less than the denominator, we call it a true fraction. When the numerator of a fraction is higher than the denominator, we call it a false fraction.

Note: to judge whether a formula is a fraction or not, the key is to meet the following requirements: the denominator of a fraction must contain letters and the denominator of a molecule is an algebraic expression. There is no need to consider whether the score is meaningful, that is, whether the denominator is zero.
