The tile back splash will be a mixture of colors of four-inch-square tiles. One third of the tiles will be "Sand," one fifth will be "Tuscan Blue," one fourth will be "Eucalyptus, " and the rest will be the color "Indian Red." What fraction of the tiles will be the color of "Indian Red"?

Respuesta :

We have

1/3 Sand

1/5 Tuscan Blue

1/4 Eucalyptus

x Indian Red

The sum of all colors must be 1

[tex]1=\frac{1}{3}+\frac{1}{5}+\frac{1}{4}+x[/tex]

we isolate the x, remember when we subtract fractions we need to have the same denominator

[tex]x=1-\frac{1}{3}-\frac{1}{5}-\frac{1}{4}=\frac{60}{60}-\frac{20-12-15}{60}=\frac{13}{60}[/tex]

ANSWER

13/60 is the fraction of tiles "Indian Red"
