By doing weighted request counting.  In the following example, for each three requests, one request will be sent to 1.2.3.4:8009 and three requests will be sent to 1.2.3.5:8009.  Apache HTTP Server keeps track internally of how many requests have been sent to each balance member, and uses that information plus the loadfactor parameter the BalanceMember directive to determine to which server to send the next request to.

ProxyPass / balancer://mycluster/
<Proxy balancer://mycluster>
    BalancerMember ajp://1.2.3.4:8009 loadfactor=1
    BalancerMember ajp://1.2.3.5:8009 loadfactor=2
    ProxySet lbmethod=byrequest
</Proxy>

Apologies for the typographical error in my answer above.  The second sentence should of course read, "In the following example, for each three requests, ONE request will be sent to 1.2.3.4:8009 and TWO requests will be sent to 1.2.3.5:8009"
