Answer:
[tex]Fraction = \frac{2}{15}[/tex]
Step-by-step explanation:
Given
Wall = 30 inches
Concrete = 16 inches
Brick = 10 inches
Limestone = 4 inches
Required
Fraction of the wall that is limestone
The fraction of limestone is calculated as follows;
[tex]Fraction = \frac{Size\ of\ limestone}{Size\ of\ wall}[/tex]
Substitute 4 for size of limestone and 30 for size of size of wall
The formula becomes
[tex]Fraction = \frac{4}{30}[/tex]
Divide numerator and denominator by 2
[tex]Fraction = \frac{4/2}{30/2}[/tex]
[tex]Fraction = \frac{2}{15}[/tex]
The fraction can not be further simplified; hence, the fraction of limestone is [tex]\frac{2}{15}[/tex]
