Since the ratio of women to men is 7 to 4, we can say that for every 7 women there are 4 men, we can also say that for a total of 11 employees (4 + 7 = 11) 7 of them are women, then we can formulate this ratio as a fraction like this:
women to employee = 7/11
Then by multiplying the total number of employees by 7/11 we can calculate how many of them are women, then we get:
women = 319×7/11 = 203
Then, a total of 203 women work for the company
