Answer:
Vinh has two wooden board. Difference of length of two boards is [tex]\frac{47}{8}[/tex] feet that is [tex]40\frac{7}{8}[/tex] feet.
Solution:
Given that
Vinh has two wooden boards
Length of one board = [tex]11\frac{3}{8}[/tex] = [tex]\frac{91}{8}[/tex]
Length of second board = [tex]5\frac{1}{2}[/tex] = [tex]\frac{11}{2}[/tex]
Difference of length of two boards = length of first board - length of second board
Difference of length of two boards = [tex]\frac{91}{8} - \frac{11}{2}[/tex]
On cross-multiplication we get,
[tex]= \frac{182 - 88}{16}[/tex]
[tex]= \frac{94}{16}[/tex] [tex]= \frac{47}{8}[/tex]
hence difference of length two boards is [tex]\frac{47}{8}[/tex] feet that is [tex]40\frac{7}{8}[/tex] feet.
