Is it possible to show me? Step by step?
Sorry, new to excel.
Your intervals are not well defined so I'll asume they are:
>=90% = green
>=70% = yellow
<70% = red
Let's assume the cells to format are A1:A10.
Select the *entire* range A1:A10 starting from cell A1.
Cell A1 will be the active cell. The active cell is the
one cell in the selected range that is not shaded. The
formula will be relative to the active cell.
Goto the Home tab>Styles>Conditional Formatting>Manage rules>New rule>Use a formula to determine which cells to format
Enter this formula in the box below:
=A1>=0.9
Click the Format button
Select the Fill tab
Select a shade of GREEN
OK
OK
New Rule>Use a formula to determine which cells to format
Enter this formula in the box below:
=A1>=0.7
Click the Format button
Select the Fill tab
Select a shade of YELLOW
OK
OK
New Rule>Use a formula to determine which cells to format
Enter this formula in the box below:
=AND(A1<>"",A1<0.7)
Click the Format button
Select the Fill tab
Select a shade of RED
OK out
