Answer:Step-by-step explanation:It looks like you’re working on calculating percentage decreases. Let’s break down the process for a few examples:Example CalculationsFrom 100 to 50:Original Value: 100New Value: 50Decrease: ( 100 - 50 = 50 )Percentage Decrease: ( \frac{50}{100} \times 100 = 50% )From 2.180 to 2.360:Original Value: 2.180New Value: 2.360Increase: ( 2.360 - 2.180 = 0.180 )Percentage Increase: ( \frac{0.180}{2.180} \times 100 \approx 8.26% )From 0.3300 to 27%:Original Value: 0.3300New Value: 27%Increase: ( 27 - 0.3300 = 26.67 )Percentage Increase: ( \frac{26.67}{0.3300} \times 100 \approx 8081.82% )From 1230 to 270:Original Value: 1230New Value: 270Decrease: ( 1230 - 270 = 960 )Percentage DecreasFrom 1000 to 4000:Original Value: 1000New Value: 4000Increase: ( 4000 - 1000 = 3000 )Percentage Increase: ( \frac{3000}{1000} \times 100 = 300% )e: ( \frac{960}{1230} \times 100 \approx 78.05% )
