Higher Order Thinking Barbara is tiling

Answer 1

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

$\frac{6}{10}$ of  x  = 18

$\frac{6}{10} \times x = 18$

$x = 18 \times \frac{10}{6}$

$x = \frac{180}{6}$

x = 30
