OpenStudy (mrnood):
when you divide by a fraction it is the same as multiplying by the 'inverse' of the fraction - that is 'turn the fraction oer and then multiply
so 12 divided by 3/4 is the same as 12 TIMES 4/3
Do the same with your question and the answer will be clear..
OpenStudy (mathmale):
Good, EXCEPT that we should be "multiplying by the 'RECIPROCAL' of the fraction - that is 'turn the fraction oer and then multiply"
"inverse" has a different meaning in algebra. y=ln x and y=e^x are "inverse functions."

correctly expressed symbolically, -21 divided by two thirds is\[\frac{ -21 }{ \frac{ 2 }{ 3 } }\]
OpenStudy (mathmale):
Invert the fraction in the denominator and then multiply the result by -21.
