Work Step by Step

We can make the ratio equal each other because the ratios between the model and the full-scale library must be equal on both sides. Thus we get, $\frac{8}{100} = \frac{x}{35}$ Cross multiple $ 8 \times 35 = 100 \times x $ $ 280=100 x $ Divide both sides by 100 $ \frac{280}{100}=\frac{100 x}{100} $ $ x=2.8$ The answer is 2.8 which is option G.
