Basically you only need one strategy. To divide a fraction (or a whole number, or a decimal) by a fraction, you multiply the first number by the reciprocal of the second number. For example, 1/3 divided by 2/5 is the same as 1/3 multiplied by 5/2.
For a proper fraction (such as 2/5) or an improper fraction (such as 7/4), to get the reciprocal you just exchange numerator and denominator. For a mixed fraction (such as 3 1/4), you convert the mixed fraction into an improper fraction first.

Oh honey, 4cm is just 4cm. You can't really express it as a fraction unless you have another unit to compare it to. It's like trying to divide apples by oranges, just doesn't make sense.
