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 quoted.

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.

4. Fraction divided by integer, denominator unchanged. 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.

5, the score divided by the score is equal to the dividend multiplied by the reciprocal of the divisor, and finally the offer score that can be reduced.
