C=B+24
B:C = 2:4 so B=24
24÷2=12
(1x12):(2x12):(4x12)

A =  \frac{1}{1 + 2 + 4}
       \frac{1}{7}
B =  \frac{2}{1 + 2 + 4}
      \frac{2}{7}
C =  \frac{4}{1 + 2 + 4}
     \frac{4}{7}

C - B = 24 feet
 \frac{4}{7}  \frac{2}{7} = 24 feet
 \frac{2}{7} = 24 feet
Question: A number multiplied by  \frac{2}{7} yields 24 feet, what is the number?

 \frac{2}{7} (x ) = 24 feet
(Multiply  \frac{7}{2} to both sides to eliminate  \frac{2}{7} )

x =  \frac{24 x 7}{2}
x =  \frac{168}{2}
x = 84 feet
