16 % of tiles are black
Solution:
Given that floor tiles come in red, blue, and black
To find: percent of the tiles that are black
From given question,
number of red tiles = 16
number of blue tiles = 5
number of black tiles = 4
Therefore, total number of tiles = number of red tiles + number of blue tiles + number of black tiles
[tex]\rightarrow 16 + 5 + 4 = 25[/tex]
Thus total number of tiles = 25
To percent of the tiles that are black, use the following formula:
[tex]\text{ percent black} = \frac{\text{ number of black tiles }}{\text{ total number of tiles }} \times 100[/tex]
[tex]\rightarrow \frac{4}{25} \times 100\\\\\rightarrow 4 \times 4 = 16[/tex]
Thus 16 % of tiles are black
