What's the reciprocal of -7 (In fraction form)

ShadowOfDeath:

Do you know what a reciprocal is?

Lazorwolf64:

well no i dont know the reciprocal

Lazorwolf64:

ive done others but this one stumped me

ShadowOfDeath:

Do you know the definition of a reciprocal though?

Lazorwolf64:

yes

ShadowOfDeath:

Okay, so it's almost the same as doing a normal positive reciprocal.

ShadowOfDeath:

Because -7 would become a positive number when it would flip to the other side.

ShadowOfDeath:

-7 is a negative whole number, and when it flips to a fraction, so does the sign.

ShadowOfDeath:

Let me show an example with the number -9. -9 is, like -7, a negative whole number.

Lazorwolf64:

oh

Lazorwolf64:

i got it thank you sooo much!!!

Lazorwolf64:

-1/7

ShadowOfDeath:

Not exactly. Close, but not quite.

ShadowOfDeath:

You flipped it correctly, but remember, when a number changes, so does the sign.

Lazorwolf64:

so its positive? 1/7?

ShadowOfDeath:

Correct.

Lazorwolf64:

oh ok thank you!!

ShadowOfDeath:

Of course!
