Question

find reciprocal of -9b over 6b+2

Answer 1

The answer z B= -1.125

Answer 2

Reciprocal is when the numerator and denominator are flipped.
So,\[\frac{ -9b }{ 6b + 2 } \] Turns into...
\[\frac{ 6b + 2 }{-9b }\]
You need to simplify it though, right?

Answer 3

ya ok thanks

Answer 4

@jazy simplify or not, you end up with a fraction bar anyway... maybe it's best to leave it be?

Answer 5

Agreed. (:

Answer 6

Well, as I'm here anyway, the reciprocal r of a fraction
\[\frac{p}{q}\]
is whatever you have to multiply to it to get 1, so...
\[ (r ) \ \frac{p}{q} = 1 \]
or
\[\huge r = \frac{1}{\frac{p}{q}}\]\[ r = \frac{q}{p}\]
Or, as was said, just flip over the numerator and denominator :)
