Question

7/9 workers in a factory are vaccinate. if 400 worker of the factory are not vaccinate. find the total number of workers in the factory​

Answer 1

Answer:

1800 workers

Step-by-step explanation:

Amount of workers which are vaccinated = 7/9

Amount of workers in a factory which are not vaccinated = 400

Fraction of workers which are not vaccinated = 9/9 - 7/9 = 2/9

If 2/9 = 400 then 1/9 = 200

Hence total no. of workers are 200 * 7 + 400 = 1800

Answer 2

Answer:

Step-by-step explanation:

Let the total workes be x

∴Vaccinated Workers = (7/9) * x

Number of Non-vaccinated workes= 400

∴ Vaccinated Workers + Non Vaccinated workers = Total Workers

∴(7/9)*x + 400 = x

400 = x-(7/9)*x

400= (9x-7x)/9

3600=2x (∵(x-7x=2x and 400*9=3600)

x=1800

There are 1800 Total Workers in factory
