in a company 95% of the workers are women if 220 people work for the company who aren't women how many workers are there in all?
dybincka [34]
So 5% of workers are not women, and 220 workers are not women, so 220 is 5% of the total workers. 220 is 5% of 4400, so there are 4400 workers in all.

Answer those two questions no silly answers 24 points
Mashutka [201]
The student who said 302 is a greater number is correct because since it has a 0 it brings the number into the hundreds while 32 is a lesser value . another example would be to make 32 you would need 3 ten blocks and 2 ones blocks and to make 302 would need 3 hundreds blocks and 2 ones blocks





if 7/2 = x/81

then you cross multiply and get

2x = 567 then divide by 2 and you get

283.5 and that's your answer
