I'm unable to see images directly. However, I can help you evaluate a proportion if you provide me with the numbers or expressions involved in Vincent's proportion.
A proportion usually takes the form of \(\frac{a}{b} = \frac{c}{d}\). To determine if it is correct, you can cross-multiply to check: \(a \cdot d\) should equal \(b \cdot c\).
Please provide the specific values or expressions for \(a\), \(b\), \(c\), and \(d\), and I can help you verify the proportion!
