The ratio of male to female employees is 3 : 4. Introduce the unknown multiplier x, making the number of males 3x and the number of females 4x, where x is a positive integer. Now translate the second sentence of the problem into algebra. “There are 5 more female employees than male employees” becomes Females – Males = 5, or 4x – 3x = 5. Solve for x: 4x – 3x = 5 x = 5 Finally, substitute into the expression for the number of male employees: 3x = 3(5) = 15. There are 15 male employees.
Using backsolving:
B)15:15+5=15:20= 3:4 (divide both side by 5)
