2 1/2= 5/2. 1 7/8= -15/8
( Dividing a positive and negative equals a negative) = -5/2 divided by 15/8
(To divide by a fraction, multiply by the reciprocal of that fraction) = -5/2x8/15
(Reduce the numbers with the greatest common factor which is 2) = -5x4/15
(Reduce the numbers with the greatest common factor which is 5) = -4/3
THE ANSWER IS -4/3
