I took the data in excel attached and sorted the women by job status. I the made three new columns: one for each job status. I then sorted each column accordingly to number of children to make a manageable database.

From that, we can calculate:

a) 307 women have full time jobs, and 178 have part time jobs. 307 + 178=485 women have jobs. 485/750=64.7%

b) 98 women with full time jobs have zero children, 16 women with no job have zero children, ...
