Answer

This is not a valid proportion; this can be proven by using the Cross Product Property.

Work Step by Step

You are given $\frac{10}{26}$ = $\frac{16}{42}$ The Cross Product Property says that the product of the means equals the product of the extremes. So: 42(10) = 26(16) 420 = 416 This is not true, so it is not a valid proportion.
