An electronic factory has a number of workers. 4/7 of the workers are skilled workers. if 3/5 of the general workers are 18 females, find the total number of workers in the factory ... (pt3)

4/7 are skilled ... 3/7 are general

3/5 of general are 18 ... 3/5 of what is 18

3/5x = 18

x = 18 * 5/3

x = 30 ... there is 30 general workers ... 18 female and 12 male

3/7 of what is 30

3/7x = 30

x = 30 * 7/3

x = 210/3

x = 70 ... so there are 70 total workers (40 skilled and 30 general)
