Question 1026977: If 420 women at a conference comprise 40% of all people at the conference, how many people were at the conference?
So far I got
(100+40)% 140*420
140/100=1.4*420=588
but also if I 420/0.4=1050

If 420 women at a conference comprise 40% of all people at the conference, how many people were at the conference?
So far I got
(100+40)% 140*420
140/100=1.4*420=588
but also if I 420/0.4=1050
If 420 women represent 40% (.4), we can set up the following proportion, with P being the number of people

at the conference: .4%2F1+=+420%2FP. I'm sure you can finish this!
