Molecule, the divisor in division is equivalent to the denominator in the fraction, the divisor in division is equivalent to the fractional line in the fraction, and the quotient in division is equivalent to the fractional value of the fraction.
Fraction divided by integer, denominator unchanged. If the molecule is a multiple of an integer, then the molecule can be divided by the integer, and finally the score can be obtained. Divide a fraction by an integer and the denominator remains the same. If the numerator is not a multiple of an integer, multiply this score by the reciprocal of the integer, and finally the offer score can be reduced.
Different denominator scores are added and subtracted, and then divided first, that is, using the basic properties of scores, different denominator scores are converted into the same denominator score, the unit of scores is changed without changing the size, and then the offer score can be reduced according to the addition and subtraction of the same denominator score.
The significance of fractional division is the same as integer division, that is, the product of two factors is known, and one factor is used to find the other factor. Dividend numerator multiplied by divisor denominator, dividend denominator multiplied by divisor numerator.
Fraction divided by integer denominator remains the same. If molecular hail is a multiple of an integer, divide it by an integer. Finally, the simplest score will be transformed into the simplest score. Fractional division is converted into multiplication of the number of parts. Dividing one fraction by another is equal to multiplying the reciprocal of this fraction, and an integer can be converted into a false fraction with the mother 1.
