Question

P and q are two integers such that p is the multiplicative inverse of -4*5 and q is the additive inverse of-5+4 find the value of p-q?

Answer 1

Answer:

Step-by-step explanation:

-4*5=  -20

multiplicative inverse of -20 is -1/20

-5+4= -1

additive inverse of -1 is 1

therefore, p= -1/20

                 q=1

p-q

= -1/20-1

= -1/20-20/20

= -21/20
