I feel dumb, I remember this math from like middle school but I can't remember the way to figure out the formula one bit. It' so basic in fact I can't find it in my textbook. It's actually a small part of a larger problem. So basically the part I am stuck on is 35/x= 2.8 and I have to find x. Any help? I did like 35/2.8= 12.5 But is that right?
