2. For two fractions with the same denominator, the fraction with large numerator is larger and the fraction with small numerator is smaller.
Method of comparing scores
1, "denominator" method: first divide two scores with different denominators into two scores with the same mother number, and then compare them according to "two scores with the same denominator, the score with the larger numerator is larger".
2. "Isomer" method: first divide the scores of two molecules into the same scores of two molecules, and then compare them according to "the scores of two molecules are the same, and the scores with smaller denominator are larger".
3. "Comparative reciprocal" method: compare the size of two scores by comparing the reciprocal of the two scores. The smaller the reciprocal score, the greater the original score; The higher the reciprocal score, the smaller the original score.
4. "Division" method: the first score is divided by the second score. If the quotient is less than 1, the first score is small; If the quotient is greater than 1, the first score is large; If the quotient is equal to 1, then the two fractions are equal.
5. "Truncation" method: before comparing two scores, truncate the two scores first, and then compare the sizes of the two scores.
Multidigit size comparison
The number of digits is different from the size, and the number of digits is more than the number of digits.
The number of digits is the same as the size, and the high position is known.
Comparison of decimal sizes
The decimal size depends on the high position, and the number of hours is large when the integer is large.
If the integers are the same, there will be more decimal places and more hours.
When the deciles are the same, the greater the percentile, the longer the working time.
