Question:
One third of 84 is \(84 \times \frac{\mathrm{1} }{\mathrm{3}} = 84 \div 3 = 28\). 28 people 25 years old or younger applied for the job. Two seventh of 84 is \(84 \times \frac{\mathrm{2} }{\mathrm{7}} = 24\). 24 people who were at least 50 years old applied for the job. 84 - 28 - 24 = 32. 32 people applied for the job who were between 25 and 50.
