Bebo wants 6/10 of floor tiles to be red. If she uses 18 red tiles, how many square tiles will be used to cover the floor. Show an area model
0.6x = 18
x = 30
I do not know
18. ----- 10
To determine how many square tiles will be used to cover the floor, we can use the information that Bebo wants 6/10 (or 60%) of the floor tiles to be red.
Step 1: Calculate the total number of floor tiles
Since Bebo wants 60% of the floor tiles to be red, we can assume that the remaining 40% will be other colors. Therefore, the total number of floor tiles can be represented by 100%.
Step 2: Determine the number of red tiles
We know that Bebo uses 18 red tiles. To find the full number of tiles, we need to set up a proportion using the percentage of red tiles:
Red tiles / Total tiles = Percentage of red tiles / 100%
Let's substitute in the given values:
18 / Total tiles = 60% / 100%
Step 3: Solve for the total number of tiles
To solve the proportion, we can cross-multiply and then solve for the variable:
18 * 100% = Total tiles * 60%
Simplifying the equation:
18 = Total tiles * 0.6
Now, divide both sides of the equation by 0.6 to isolate the variable "Total tiles":
Total tiles = 18 / 0.6
Calculating the expression:
Total tiles = 30
So, Bebo will use a total of 30 square tiles to cover the floor.
To show an area model of this situation, imagine a rectangular area representing the floor. Divide the floor into 10 equal parts vertically and horizontally. Shade in 6 out of the 10 horizontal sections to represent the red tiles. Each horizontal section would then be covered by 3 square tiles. In this case, there would be 5 horizontal sections covered by square tiles of other colors.
