Answer:
Gigi will need to buy at least 10 packages of straws to have enough to finish her art project.
Explanation:
So, we already know that Gigi is going to need 243 straws for her project. We are also given the information that there are 25 straws in a package. This is a simple division equation that can be represented by:
243/25=?
Now, the thing is, we know 243 is not divisible by 25, aka, it won't go in evenly. So, we will have a decimal.
243/25= 9.72
Since we know that we have to get at least 9.72 bags, and that the straws are only sold in pieces of 25, we must round up. She will require 10 packages. ONLY USE 9.72 if the TEACHER IS LOOKING FOR AN EXACT ANSWER WITH DECIMALS.
