We can take the cross products of the given proportion to determine whether or not the proportion is true. If the cross products are equal, then we know that the proportion is true. $\frac{5.6}{.6}=\frac{18}{1.94}$ $5.6\times1.94=.6\times18$ $10.864\ne10.8$ Although the cross products have nearly the same value, they are not equal. Therefore, the proportion is False.
