Proportional relationships examples math
WebbKey Concepts If two quantities are proportional to one another, the relationship between them can be defined by a formula of the form y = kx, where k is the constant ratio of y -values to corresponding x -values. The same relationship can also be defined by the formula x = ( 1 k) y , where 1 k is now the constant ratio of x -values to y -values. WebbTwo variables have a proportional relationship if the ratios of the variables are equivalent. Learn how to identify these relationships in this free lesson!

WebbExample 2: If m is inversely proportional to the square of n, and m = 64 when n = 3. Find m when n = 5. Solution: Given, m ∝ 1/n 2. ∴ m = k/n 2. m × n 2 = k. From 1st condition we get, k = 64 × 3 2 = 576. Now, we need to find m when n = 5. m × n 2 = k, m × 5 2 = 576. Thus, m = 576/25 = 23.04. Therefore, m = 23.04 when n = 5.

Find the value of the constant of proportionality if a = 7 and b = 49, Solution: Given that b = 49 and a = 7 ‘b’ is directly proportional to ‘a’. Therefore the formula we will use is b = ka. k = b / a k = 49/7 k = 7.
