    1 decimeter = 10 centimeters So: 5 decimeters = 50 centimeters

    To find the ratio of how much longer something is than something else, you divide it. For example: \[\frac{100ft}{10ft} = 10\] Which means that something 100 feet long is 10 times longer than something 10 feet long.

    Well, you can only divide values with like terms, and centimeters ≠ decimeters. Also, to avoid confusion, put the larger number on top when dividing.

    Well, if you divide: \[\frac{5 decimeters}{4centimeters}\] You'll get the ratio of 5 decimeters to 4 centimeters, which isn't what the problem's asking for. It wants to know their relative distances, so you need to change 5 decimeters into the equivalent number of centimeters, using the following equation: \[x centimeters = 10xdecimeters\] Or, in other words, there are 10 centimeters in every decimeter.

    Sorry, the equation is actually: \[centimeters = 10x decimeters\] Where x is the number of decimeters

    Close. Leave the bottom number as 4, since it's already in centimeters.
