If a number is multiplied by a true fraction, the product must be larger than that number______ (judge right or wrong)

If a number is multiplied by a true fraction, the product must be larger than that number______ (judge right or wrong)

If the true fraction of the second factor is less than 1, the product must be smaller than the number. If the number is 0 and the product is still 0, the product is equal to the number. Therefore, if a number is multiplied by the true fraction, the product must be larger than the number. The answer is wrong

The product of a true fraction and a false fraction must be larger than the true fraction______ (judge right or wrong)

The answer is: the product of x = 12 is equal to that of x = 13

The product of a number multiplied by a true fraction must be less than this number______ (judge right or wrong)

For example, 0 × 12 = 0, the product is equal to this number
