Answer:

The fraction of tiles that will be the color of "sand" is 23/60

Step-by-step explanation:

we know that

The sum of the fractions of the tiles must be equal to 1

Let

x ----> the fraction of tiles that will be the color of "sand"

we have that

[tex]\frac{1}{4}+\frac{1}{6}+\frac{1}{5}+x=1[/tex]

solve for x

Find the Least Common Multiple of denominators

[tex]LCM=(2^2)((3)(5)=60[/tex]

Multiply both sides by 60

[tex]\frac{60}{4}+\frac{60}{6}+\frac{60}{5}+60x=60[/tex]

simplify

[tex]15+10+12+60x=60[/tex]

[tex]60x=60-37\\60x=23\\x=\frac{23}{60}[/tex]

therefore

The fraction of tiles that will be the color of "sand" is 23/60
