Answer:

23%

Step-by-step explanation:

Givens:

  • 42 black tiles.
  • 35 blue tiles.
  • 23 red tiles.

The percentage of the number of red tiles is obtained by dividing all red tiles with the total number of tiles, that is

[tex]\frac{23}{42+35+23}=\frac{23}{100}= 0.23 \ (or \ 23\%)[/tex]

Therefore, all red tiles in the mural represent a 23% of all tiles.
