Two capacitors of 0.0003μF and 0.0006μF are connected in series, find their combined capacitance.

After solving on my own
I discovered the explanation is wrong in terms of simplyfying 1/c =(1/0.003)+(1/0.0006)
Finding the lcm we should have 1/c=(2+1/0.0006)
=3/0.0006
Reciprocating we have
C=0.0002uf

And not
1/c= 0.0002+0.0001/0.0006
1/c=0.0003/0.0006
Reciprocating
C=0.0006/0.0003
Will gives gives (solving by heart or using calculator)
C=2uf
Which is wrong and not in the question
The from the explanation the working doesn't justify the answer

Please make correction

The right answer is not in the question as 0.0006/0.0003 gives 2 and not 0.0002

To calculate lcm of two numbers
Just divide the multiplication...by the addition.

0.0006 × 0.0003/ 0.0006 + 0.0003
