The ratio of women to men working for a company is 5 to 7. If there are 140 men working for the company, what is the total number of employees

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
