4/3 long is each of the 7 smaller boards.
What is unitary method?
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
According to the question
Diego cut 7 smaller boards of equal length from a board that is 9 1/3 feet long.
9 1/3 = 28/3
Using unitary method
X = [tex]\frac{\frac{28}{3} }{7}[/tex]
X = [tex]\frac{28}{3} \times\frac{1}{7}[/tex]
X = [tex]\frac{28}{21}[/tex]
X = [tex]\frac{4}{3}[/tex]
4/3 long is each of the 7 smaller boards.
