Answer:
\(13/28\)
Step-by-step explanation:
Let
x-----> the shaded area
we know that
\(x+\frac{1}{4}+\frac{2}{7}=1\)
Because the complete circle represent the \(100\%\)
and
\(100\%=100/100=1\)
solve for x
Multiply by \(28\) both sides
\(28x+7+8=28\)
\(28x=28-15\)
\(28x=13\)
Divide by \(28\) both sides
\(x=13/28\) ----> fraction irreducible
