Answer:
11: If 3/4 = n/12, then n =
a. 6
b. 9
c. 15
d. 18
Explanation:
3/4 = n/12 can also be written as 3:4 = n:12.
Let us find the product of the means, and the product of the extremes, and their products must be equal.
Means: (4) (n)
Extremes: (3) (12)
(4)(n) = (3)(12)
4n = 36
[tex]\frac{4n}{4} =\frac{36}{4}[/tex]
n = 9
