Question:
Barbara is tiling her craft room with square tiles. She wants 6/10 of the square tiles to be red. If she used 18 red tiles, how many square tiles will be used to cover the floor . Draw an area model to help solve
Answer:
The number of tiles required to cover the floor is 30
Step-by-step explanation:
Given:
Fraction of tiles Barbara wants to be red = 6/10
Total number of red tiles used = 18
To Find:
The number of tiles used to cover the tiles = ?
Solution:
Let the number of tiles required to cover the floor be x,
Then
[tex]\frac{6}{10}[/tex] of x = 18
[tex]\frac{6}{10} \times x = 18[/tex]
[tex]x = 18 \times \frac{10}{6}[/tex]
[tex]x = \frac{180}{6}[/tex]
x = 30
