Me and my family are getting ready for halloween party. We knew that my moms family was coming. What we need to know is how many tables and chairs we need to get. There are 20 uncles coming and 30 aunts and 20 kids. Find the if unit rate if needed and then find the rate of all.
what you can do mostly what I can do to get the answer is to first find the unit rate if I need to then multiply the unit rate to get the answer then get the answer then you find out the actual rate and correct number for chairs and tables.
But I would do something like an example to find out if my answer is right or i should try again.
