So I've got to do finding the Least Common Multiple of rational decimals, and the examples are all telling me that you have to take the power that represents the greatest number of decimal places in any term of the equation. The examples say that for the problem 1.12c + 2.06 = 9.9. Since the greatest spot is 2 to the right of the decimal, it states that the power of ten that should be used is 10 for each number that has 2 to the right of the decimal. Two numbers have that, so it should be 10 x 10. It obviously says the LCM should be 100.
This is where I start having trouble. If a problem only ever goes one space to the right, what power of ten should be used? If all three numbers all have one space to the right, it should be that number times itself, times itself, right? So what the heck am I not getting?
