Need someone who can Answer some questions and show me how to display data pulled via API

PLEASE READ BEFORE BIDDING! This is for an English Speaker only. You must be from a country where English is your first language. This is only because it will be a conversation we will be having and not really a project as I just need a few questions answered (don’t even try to google it, it’s not a google type of question) The data I get is (example) {code: 200, info, success, data {“a”: 200, “b”:999, “c”:0.031}} and this data is updated live so I also need it to update live every second or whatever the least amount of time is. My main developer is sick and recovering and I posted a project here but that freelancer failed to make what I needed so instead I decided to wait till my main developer is back and just need live data from a url displayed on my site and an extra line that does a simple “/“ calculation. How do I display a, b and c and have an extra line d which does simple calculation of let’s say a/b. So it’s displayed on front end and in a modern design. That is one question and other questions will be similar. Other questions will be very easy to answer if you can answer the main one. I am not what the skills are that is required to answer these but I am guessing it’s one of the 4 I put.
