not changing the sign

no 5 is not the same thing as -1/5
OpenStudy (freckles):
why are you guessing...
we found the answer above
OpenStudy (adovbush):
ohh so its D?
OpenStudy (freckles):
the reciprocal of 1/5 is 5/1 which is just 5 since 5 divided by 1 is 5
OpenStudy (freckles):
this is why I said congrats earlier I thought you understand 5 divided by 1 is 5...
