The answer process is as follows:

Suppose the volume of water is 1, and when it turns into ice, it is1+110 =110.

The mathematical expression of how much the volume of ice water is reduced is: (110-1) ÷110.

In which:111=110,1/10/0/0.

That is to say, the volume of ice turned into water is reduced by111.

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 the offer score can be reduced.

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.
