there are 280 female workers and 140 male workers working in a factory.3/5 of the workers are foreign workers and 1/2 of the foreign workers are female.calculate how many local workers in the factory are female.
First, find the total number of workers. (280 + 140 = 420)
Three fifths of this total are foreign. (420 * 3/5 = 252)
Half of the foreign workers are female. (252/2 = 126)
Since 126 of the 280 female workers are foreign, the remainder must be local. (280 - 126 = 154)
