Solution:
Given:
The proportion,
[tex]\frac{17}{8}=\frac{7}{u}[/tex]
To solve for u,
[tex]\begin{gathered} \text{cross multiply the equation,} \\ 17\times u=8\times7 \\ 17u=56 \\ \\ \text{Dividing both sides by 17 to get u,} \\ u=\frac{56}{17} \\ u=3.2941176 \\ \\ To\text{ the nearest tenth,} \\ u=3.3 \end{gathered}[/tex]
Therefore, the value of u, to the nearest tenth is 3.3
