What are these dual wan loadbalancing configuration numbers

Hi,

I have dual wan with wan and usb

I want load balancing but i don't properly understand load balancing configuration numbers



So if i write 5 and 1 :

does that means for 5mb on primary it will consume 1mb from secondary ?

Or will that mean secondary will be five times slower in speed ?

Can you please help me understand what those numbers actually mean. .
