negative one. 1/1 = 1 a positive/negative = negative
negative one third
Yes.
reciprocal of a negative is still a negative, and 2 and a quarter can be rewritten as 9/4. The reciprocal of this number is 4/9. Therefore, the reciprocal of -2 and a quarter is -4/9.
The reciprocal of -1/10 is -10, and the negative of -10 is 10 .
negative one over one
It would be the negative of the negative reciprocal. And since the negative of a negative is a posivie, it is the positive reciprocal.. For example, if the slope was -3, the other would be 1/3.
To get the reciprocal of a fraction, exchange the numerator and the denominator (the top and bottom parts). The reciprocal of a negative fraction is also negative.
The negative reciprocal of zero would be any undefined fraction. 0/x=0 negative reciprocal: -(x/0)= undefined.
Taking the reciprocal (multiplicative inverse) does not affect the positive or negative status of an integer. So the reciprocal of a negative number is negative and the reciprocal of a positive number is positive. The reciprocals will be opposites (positive/negative) just as the original numbers were.
one slope is the negative reciprocal of the other
The negative reciprocal of any gradient gives the gradient of the line perpendicular to it. If you had a line of gradient 2, the negative reciprocal would be -1/2 Just change the sign on the number and flip the number/fraction to get the negative reciprocal.
