why all the stupid $ signs?
A:B = 4:5
If there are 4x packages of A and 5x packages of B, then there are
So, in all, there are
2*4x + 3*5x white balls
3*4x + 4*5x orange balls
So white : orange = 23/32

You can not use x for all of them. You have to change the variable. As for Bob , please do not put your homework questions in the internet. No searching up the answers.
