Question

1

Answer 1

\[\frac{ 1 }{ a }=\frac{ 1 }{ b }+\frac{ 1 }{ c } \] solve for c

Answer 2

Subtract 1/b from both sides

Answer 3

The best thing you could do to start with is multiply both sides by \(\rm abc\). That way, the fractions get cleared. :D

Answer 4

so is it \[\frac{ a }{ b }\]

Answer 5

Please show how you managed that result. No guessing. Show your actual work.

Answer 6

\[\frac{ 1 }{ a }=\frac{ 1 }{ b }+\frac{ 1 }{ c }\]\[\frac{ 1 }{ a }-\frac{ 1 }{ b }=\frac{ 1 }{ c }\]\[\frac{ b }{ ab }-\frac{ a }{ ab }=\frac{ 1 }{ c }\]\[\frac{ b - a }{ ab }=\frac{ 1 }{ c }\]\[\cdots\]

Answer 7

or c = ab/(b-a)
