so women:men=5:7 for every 5 units of women, there are 7 units of men so there are 140 men and that equals 7 units so 140=7 units solve for 1 unit 140/7=20 1 unit=20 women=5 units 5 times 20=100 women=100 total=women+men=100+140=240 another way would be to add up the units (5+7=12) and multiply by the amount per 1 unit
