## Explanation

Conditional formatting rules are evaluated in order.

- For each cell in the range B5:B12, the first formula is evaluated. If the value is greater than or equal to 90%, the formula returns TRUE and the green fill is applied. If the value is not greater than or equal to 90%, the formula returns FALSE and the rule is not triggered.
- For each cell in the range B5:B12, the second formula is evaluated. If the value is greater than or equal to 80%, the formula returns TRUE and the yellow fill is applied.
- For each cell in the range B5:B12, the third formula is evaluated. If the value is less than 80%, the formula returns TRUE and the pink fill is applied.

The "stop if true" option is enabled for the first two rules to prevent further processing, since the rules are mutually exclusive.
