What are you given about the numbers \(\displaystyle a,b,c,\;d\;?\) Are they positive?If a/b < c/d
Show a/b < (a+c)/(b+d) < c/d
If a/b < c/dHi folks, I’m going through a precalc book as a refresher and I guess my brain not operating as good as it used to. Got stuck on the following:
If a/b < c/d
Show a/b < (a+c)/(b+d) < c/d
Hint would be appreciated!
Thanks
If a/b < c/d
Show a/b < (a+c)/(b+d) < c/d Hint would be appreciated!
Rearrange & add one to both sides:Thanks for the replies. I did forget to include that a,b,c,d are all positive numbers.
If a/b < c/d
Show a/b < (a+c)/(b+d) < c/d
Hint would be appreciated!
