Answer:

  45%

Step-by-step explanation:

The percentage change is calculated using ...

  percent change = ((new value) - (old value))/(old value) × 100%

For your numbers ...

  percent change = (11 -20)/20 × 100% = -9/20 × 100% = -45%

The negative sign indicates the change is a decrease. Here, you're asked for the amount of decrease.

The percent decrease is 45%.
