the three salespeople for a local advertising firm are lola, ahmed, and tommy. lola sold $2030 in ads, ahmed sold $1540, and tommy sold $1800.
what fraction of the total sales did each salesperson sell?

First, find your total sales. You do this by adding all the sales together, 2030+1540+1800=5370. Now, for each person, divide their sales by total sales.
Lola) 2030/5370=203/537≈0.378=37.8%
Ahmed) 1540/5370=154/537≈0.287=28.7%
Tommy) 1800/5370=180/537=60/179≈0.335=33.5%
