Breakdown of Telenet invoice

We have a Telenet package for internet and mobile phone use. Part of this is for private use, part is for business use for my sole proprietor business, and a small part is for business use for my wife’s secondary occupation. The bill is in my name and has been paid from my account. How and in what proportion should I record the different parts in my accounts? How do I record the private portion? What about the portion intended for my wife’s secondary occupation?
