The loudness (L) of sound in decibels is related to intensity (Imeasured in watts per square centimeter by the equation: L = 10log/ 1
10-16).

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
