Multi Wan on RB450G

Hi guys, im new on the forum and to routerOS. Im running a RB450G with MikroTik RouterOS 4.14. Right now i have 2 WANs connected to the unit on ethernets ports 4 and 5. While LAN is connected on ethernet port 2.

One of the WANs, is a simetric 2mb fiber connection with a static IP. While the other one is a 5mb/256k cable connection, with a dynamic IP. Right now the traffic is going through the cable connection.

I need to set up a single IP to run on the other WAN, how do i do this?

Thanks for your help.
