You want to use square tiles to cover the top of a table you're making. The top is 30 inches by 18 inches. What is the side measure of the largest-sized square tile you can use to cover the tabletop without any overlap or cutting?
round to the nearest tenth please
+67 well, !'m not good at explaining but you need to find the GCF of the numbers
30
1.2, 3, 5, 6, 10,16, 30
18
1, 2, 3, 6, 9, 18
So, all i did was write out the factors and found the GCF
Answer: 6in

-DBZ
+128731 Here's another way to see this
Let the side of the tile = x
Then the number of tiles that will cover the 30 inch dimension is 30/x
And the number of tiles that will cover the 18 inch dimension is 18/x
And we want x to be as large as possible
So....the GCF of 18, 30 = 6 inch tile....just as DBZ found !!!!
