Answer 1

Explanation:

The number of farms in Oregon in 1982 were approximately 6.5 million​ farms. There was a decrease in the number of farms such that in 2014, the number of farms in Oregon were only approximately 5.2 million farms. The decrease in the number of farms would be

6.5 million - 5.2 million = 1.3 million.

The percent of decrease in the number of farms would be expressed as

Decrease/previous number of farms × 100. It becomes

1.3/6.5 × 100 = 0.2 × 100 = 20%
