Answer and step-by-step explanation:
"Fill the blank with the number that will complete the proportion."
3 : n = 9 : 30
To find the missing term, first, separate the means and extremes:
(3)(30) = (n)(9)
Second, multiply:
90 = 9n
To remove the 9 from n, the third step, divide both sides with 9:
[tex]\frac{90}{9} = \frac{9n}{9}[/tex]
10 = n
Tada!! The missing term is 10.
I hope it helps :).
