1/3rd of the workers before the new hires were women because 1 - (2/3) = 1/3
There were 30 women working for the company before the new hires
There are now 40 women working for the company because 30 + 10 = <<30+10=40>>40
There are 100 people working for the company because 90 + 10 = <<90+10=100>>100
The proportion of women working in the company is .4 because 40 / 100 = <<40/100=.4>>.4
The percentage of women working in the company is now 40 because .4 x 100 = <<.4*100=40>>40
