Plz the price of a technology stock was 9.83 yesterday. today, the price fell to 9.72 . find the percentage decrease. round your answer to the nearest tenth of a percent.@nilbert

The percentage change can be found from
  percent change = ((new value)/(original value) - 1) × 100%
For your numbers, that is
  percent change = ((9.72/9.83) - 1) × 100% = -0.01119... × 100%

The decrease in value is about 1.12%
