The analysis process is as follows:
(1) Find the percentage of one number to another and divide it into two complements. The first step is to find out the percentage of one number to another.
2 is a fraction of 8. The mathematical expression is 2/8= 1/4.
(2) Step 2: Convert the percentage.
1/4=0.25× 100%=25%。 Thus, 2 is 25% of 8.

Fractional addition and subtraction
1, add and subtract fractions with the same denominator, the denominator remains the same, that is, the decimal unit remains the same, and add and subtract numerators to reduce the bid score.
2. Add and subtract the scores of different denominators, divide them first, that is, use the basic properties of scores to convert the scores of different denominators into the scores of the same denominator, change the unit of scores and keep the size unchanged, then calculate by adding and subtracting the scores of the same denominator, and finally make a quotation score that can be reduced.
Multiplication and division
1, the fraction is multiplied by the integer, the denominator remains the same, the numerator is multiplied by the integer, and finally the score that can be reduced is reported.
2. The score is multiplied by the score, the numerator is multiplied by the numerator, and the denominator is multiplied by the denominator, and finally the offer score that can be reduced is obtained.
3. Fraction divided by integer, denominator unchanged. If the numerator is a multiple of an integer, divide the numerator by the integer, and finally you can reduce the number of offer points.
