Question

solve the following proportion for u.
\\(\frac{5}{u} = \frac{11}{7}\\)
round your answer to the nearest tenth.
\\(u = \square\\)

Explanation:

Step1: Cross-multiply to eliminate fractions

$5 \times 7 = 11 \times u$

Step2: Calculate left-hand side product

$35 = 11u$

Step3: Isolate $u$ by dividing by 11

$u = \frac{35}{11}$

Step4: Compute decimal and round to nearest tenth

$u \approx 3.2$

Answer:

$u = 3.2$
