How can you write any rate as a unit rate?

The problem must have two terms, and you must be asked to determine how much of one term exists per unit of the other term. Rewrite the data as a division problem. The first term in the problem—the amount you are trying to calculate per unit—will become the numerator (top number). The second term—the unit—will become the denominator (bottom number). Divide both values by the denominator. To find the unit rate, simply solve the newly written division problem. Doing so will reduce the denominator to "1." Write the solution. You should now have your final answer ready.

Understanding what? lol
