If u/v = x/y, then (u+v)/ (u-v) = (x+y)/(x-y) (also known as the componendo dividendo rule. In notation, an inverse proportion is written asy 1/x. A ratio is a comparison of the value of two numbers. a/(b + c) = b/(c + a) = c/(a + b) and a + b + c 0, then a = b = c. a/b= c/d(a + b)/(a - b) = (c + d)/(c - d), which is known as componendo -dividendo rule. For example, consider two ratios to bea:bandc:d. In order to find the continued proportion for the two given ratio terms, we will convert their means to a single term/number.
