The following statement is correct () A. Positive and negative numbers are called rational numbers. B. 0 is an integer but not a positive number. C. 0 is the smallest number. D. 0 is the smallest positive number

The following statement is correct () A. Positive and negative numbers are called rational numbers. B. 0 is an integer but not a positive number. C. 0 is the smallest number. D. 0 is the smallest positive number


0 is an integer, but it is not a positive number



The following statement is correct ()
A. If the sum of two rational numbers is positive, then one of the two numbers must be positive. B. if the difference between two rational numbers is negative, then the subtracted is negative. C. The product of two rational numbers must be greater than one of the factors. D. if the quotient of two rational numbers is greater than 1, then the divisor is greater than the divisor


A. Correct; B, 1-2 = - 1, the subtracted is a positive number, the option is wrong; C, two negative numbers multiplied, the product must be greater than each factor, the option is wrong; D, (- 3) / (- 1) = 3, the divisor is less than the divisor, the option is wrong



If a is a rational number, then the correct statement of - A is - A is negative - A is positive - A is negative
If a is a rational number, then what is right about - a
-A is a negative number - A is a positive number - A is the opposite of A
-A is a positive or negative number


The third is right
