Ratio between two sets of numbers? I have two sets of numbers. The first set is 1 to 4. The second set is 0 to 190. What is the calculation to get the proportionate number in the second set if a number in the first set is, for example, 1.2? Math is not my forte!

It is $\displaystyle\frac{1.2-1}{4-1}\cdot (190-0) +0$.
