Question

solve the following proportion for u.
\\(\frac{3}{8} = \frac{u}{11}\\)
round your answer to the nearest tenth.
\\(u = \square\\)

Explanation:

Step1: Cross-multiply to isolate $u$

$3 \times 11 = 8 \times u$

Step2: Calculate left-hand side

$33 = 8u$

Step3: Solve for $u$

$u = \frac{33}{8}$

Step4: Compute and round to nearest tenth

$u = 4.125 \approx 4.1$

Answer:

$u = 4.1$
