Answer:
Cross Products Property of Proportions states that the product of the means is equal to the product of extremes.
i,e [tex]a : b : : c : d[/tex]
Also, in the proportion the first (a) and the last terms(d) are called the extremes, whereas the second(b) and the third terms(c) are called the means.
Given the proportion:
[tex]1 : 2 = 4 : 8[/tex]
First term = 1
Second term = 2
Third term = 4
Fourth term = 8
By definition;
The product of means = [tex]1 \times 8 = 8[/tex]
The product of extremes = [tex]2 \times 4 = 8[/tex]
Therefore, the product of both the means and the extremes is, 8
