Question

Set up all proportions from the numbers 9, 150, 105, 1750.

Answer 1

All proportions are:
9 : 150 = 3 : 50
9 : 105 = 3 : 35
9 : 1750
150 : 105 = 10 : 7
150 : 1750 = 3 : 35
105 : 1750 = 3 : 50

Thus, all proportions that can be formed are:
3 : 50, 3 : 35, 10 : 7, 9 : 1750, 1750 : 9, 7 : 10, 35 : 3 and 50 : 3
