This question is incomplete, the complete question is;
Nine pieces of 8-in. × 12-in. duct that is 2[tex]\frac{2}{3}[/tex] ft in length is needed for a building. What is the total length (in ft) needed?
Answer:
the total length needed is 24 ft
Step-by-step explanation:
Given the data in the question;
the length of one piece of 8-in. × 12-in. duct is 2[tex]\frac{2}{3}[/tex] ft
Now to find the total length for nine pieces of the duct;
we simple multiply 2[tex]\frac{2}{3}[/tex] ft by nine
so
Total length = 9 × 2[tex]\frac{2}{3}[/tex]
we convert the mixed fraction to improper fraction
2[tex]\frac{2}{3}[/tex] = 8/3
so
Total length = 9 × (8/3) ft
Total length = 24 ft
Therefore, the total length needed is 24 ft
