Work Step by Step

Given a ratio of 2:3:5 and their combined annual salaries amount to $124,500. You take the total combined number (124,500) and divide it by the total parts within the ratio, in this case 10 (2+3+5) 124,500/10 = 12,450. Using this number you multiply by each part in the ratio to get the salary of each worker. 12,450 x 2 = Secretary. 12,450 x 3 = Salesperson. 12,450 x 5 = Vice President.
