Yes it is. The reciprocal is 1 divided by the number, and the opposite is to change the sign. -(1/1) = -1 ■
positive x positive = positive negative x negative = positive positive x negative = negative negative x positive = negative The same rules apply for dividing, since dividing is actually multiplying by the reciprical.
basically, if you have a number, you make the denomenator as its numerator and numerator as its denomenator. for example, the negative reciprical of 2 is -1/2
When you divide fractions, you actually multiply them and use the reciprical. For example: 3/8 divided by 1/5 3/8 x 5/1 ------> 5/1 is the reciprical of 1/5 (you just flip them) so 3/8 x 5/1=15/8 which = 1 and 7/8 <------that is your answer
