60 points if you do everything I say here please! St Augustines grass can grow at the rate of 4/7 centimeters per week How many weeks will it take to grow 12\7 centimeters?

So I don’t know a lot about this because I learned this last grade kind of how to do this but then ended up forgetting since I finished math a while before my other classes and haven’t done it in around a year lolso I don’t know much about that would anyone kindly explain (in words that someone who knows nothing about this could understand) that way I can use this in other problems also? If you do I’ll thank you and give 5 stars enjoy the 60 points :) and thank you to whoever answers
