How to Reciprocal Every Number in Cell of a Whole Column in Libreoffice Calc?

I want to make reciprocal of a whole columns cells of libreoffice calc. I can do this by manually. Are there any way which makes reciprocal every cells element(number) of a whole column or row?

In the following figure I want to get the C column from B column:

enter image description here

Solution

To make it exactly as shown in the image, put this in cell C1:

="1/" & B1

Then fill down by dragging the lower right hand corner of the cell down to row 12.

To calculate the reciprocal, put this in cell C1 instead:

=1/B1
