Question
Set up all proportions from the numbers $9, 150, 105, 1750.$
✓
Answer
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 $50 : 3$
$9 : 150 = 3 : 50$
$9 : 105 = 3 : 35$
$9 : 1750$
$150 : 105 = 10 : 7$
$150 : 1750 = 3 : 35$
$105 : 1750 = 3 : 50$
Thus, all proportions that can be formed are:
$3 : 50, 3 : 35, 10 : 7, 9 : 1750, 1750 : 9, 7 : 10, 35 : 3$ and $50 : 3$
