Let x be the number of men workers.
x+40 be the number of women workers.
x + (x+40) = 350
x + x + 40 = 350
2x + 40 = 350
2x = 350 - 40
2x = 310
x = 310/2
x = 155
Therefore, the number of men workers are 155.
To get the rate, divide 155 by 350.
R = 155/350
R = 0.4429 or 44.29%
Therefore, there are 44.29% of men workers in the factory.
