Workers get 1/7 on the first day.
The next day, the workers got 2/7= 1/7+ 1/7.
On the third day, the workers got 3/7=4/7- 1/7.
And so on.
Extended data:
1, different denominators:
Fractions with different denominators are added: the fractions with different denominators are added and divided equally, and then the numerator is added, with the denominator unchanged. The calculated result, divisible offer score, is a false score and should be changed into a score or an integer.
Subtraction of Fractions with Different Denominators: Subtract the Fractions with Different Denominators, then divide them equally, and then subtract the numerator, with the denominator unchanged. The result of calculation is that the number of offer points that can be reduced is a false score, which should be converted into a score or an integer.
2. Same denominator:
Addition of fractions with the same denominator: As long as the numerator is added and the denominator remains the same, the calculated result can be simplified, that is, a false fraction, which should be converted into fractions or integers.
Subtraction of fractions with the same denominator: the numerator should be subtracted and the denominator should not be changed. The calculated results, which can be simplified, are false fractions and should be converted into fractions or integers.
