A reduction of 64.3 percent

Step-by-step explanation:

Initial price of Brent crude oil=$140 per barrel

Final price of Brent crude oil=$50 per barrel

The percentage change in price=((Final price-Initial price)/(Initial price))×100

(50-140)/140=-0.6429×100=-64.29

Rounding off to tenth of a percent=10/100=0.1

-64.29=-64.3 since 64.29 is nearer to 64.3 than 64.2

-64.3 percent implies a reduction of 64.3 percent

There was a reduction of 64.3 percent
