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)

Respuesta :

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)
