Answer: [tex]\frac{3}{10}[/tex] of the mural is sky blue.
Step-by-step explanation:
Let x be the full portion of mural.
Since, [tex]\frac{4}{5}[/tex] of mural is painted in shades of blue.
Therefore, the blue portion=[tex]\frac{4}{5}x[/tex]
Also, Three eighths of the blue area is sky blue.
Therefore, the portion of the mural is sky blue=[tex]\frac{3}{8}\times\frac{4}{5}x[/tex]
The portion of the mural is sky blue=[tex]\frac{12}{40}x[/tex]
Simplify, by dividing numerator and denominator by 4, we get
The portion of the mural is sky blue=[tex]\frac{3}{10}x[/tex]
