Highlighting cells based on a formula

[Kudrun]

Hello. I hope someone is able to help me. This seems simple (and I'm sure it is), but I cannot work it out.

I have 2 columns of figures (A and B). I want to highlight in red the cell (A2) in column A, if "B2 divided by A2 is less than 1.1 or greater than 2". So in the example below, A2 and A5 would be highlighted in red.

A	B	B/A=
101	213.59	2.11
334	458.23	1.37
266	430.86	1.62
847	517.6	0.61

<tbody>
</tbody>

I've tried creating a conditional formatting for column A, like =IF(B2/A2<1.1) or =IF(B2/A2>2), but it doesn't work and I need to include them together like =IF(B2/A2<1.1,IF(B2/A2>2)) and also affect the entire column, not just Row 2 (using/ not using "$" perhaps?).Can some one help me please. I'm clearly missing something or writing the formula wrong.

Thanks.

=AND(OR(B2/A2>2,B2/A2<1.1),B2<>0)

Apply to A2:A1000 or something sensible.

This is perfect. Thank you so much for such a quick response.

Worked like a charm.
