Conditional format formula to highlight cells with a percentage

[fumusic]

i have set up conditioning formatting to highlight cells in a row yellow if they are 3 or under. I have also added another rule to colour the cells white if blank so it will only colour cells within the table. However, the columns with the weekly percentages are being affected as they are being read as below 4. Can you please give me a formula to recognise a cell with a percentage format and to colour it white thus removing the yellow highlight?
Thanks.

Use

=AND(B3<>"",B3<4)

with the applies to range as
=$B$3:$H$5,$J$3:$P$5

For the yellow ones
Remove all the yellow formulas

Select the entire range

=AND(B3<4,COLUMN()<>9,COLUMN()<>17)
format as yellow

thanks for the responses. sorry, i forgot to mention that the weekly columns will be ongoing. That's why I am formatting the entire rows. will these formulas still work?

In that case select B3 to whatever & use

=AND(B3<>"",B3<4,B$2<>"%")
