Solve for the unknown.
Problem 1 :
3 : n = 5 : 20
Problem 2 :
a : 42 = 5 : 6
Problem 3 :
50 : 75 = x : 1/2
Problem 4 :
7 : 3.5 = 21 : z
Problem 5 :
0.6 : g = 0.78 : 0.325
Problem 6 :
7/8 : 3/16 = t : 5/8
Use proportions to solve the following problems.
Problem 7 :
A box of 500 vitamin C tablets sells for $4.80. How much would 125 tablets cost?
Problem 8 :

1) n = 12
2) a = 35
3) x = 1/3
4) z = 10.5
5) g = 0.25
6) t = 35/12
7) n = $1.2
8) n = 108 cans of soup
9) n = 2750 microwave ovens
10) a) x = $6300, x = $10500
