The graph below shows the number of active-duty U.S. military personnel, in thousands, in 1990 and 2014 . Which branch of the military had the greatest percent decrease in personnel from 1990 to 2014 ? What was the percent decrease for this branch of the service? Round to the nearest tenth of a percent. Number of Active-Duty U.S. Military PersonnelSOURCE: Department of Defense

To determine

The military branch which had the greatest percent of decrease in personnel from 1990 to 2014

Explanation

Given Information:

The graph shows the number of active-duty US military personnel in thousands from year 1990 to 2014

Calculation:

Calculate the decrease in active duty US military personnel of Army

Decrease in number of members from 1990 to 2014 ,

732516=216

Apply basic percent equation formula

PB=A

Here, P (percent) is unknown, B(base) is the number active Army personnel in year 1990 , 732 and A(amount) is the number of active ARMY personnel decreased till 2014 , 216

P×732=216P=216732P=0.295

Thus, percent decrease in US Army personnel from 1990 to 2014 is 29.5%

Calculate the decrease in active duty US military personnel of Navy,

Decrease in number of members from 1990 to 2014 ,

579319=260

Apply basic percent equation formula

PB=A

Here, P (percent) is unknown, B(base) is the number of active Navy personnel in year 1990 , 579 and A(amount) is the number of active Navy personnel decreased till 2014 , 260

P×579=260P=260579P=0.449

Thus, percent decrease in active Navy personnel from 1990 to 2014 is 44
