Question

Determine the missing value in the table.

  1. 15
  2. 3
  3. 1 third
  4. 9

hintHint:

Constant of proportionality is the constant value of the ratio between two proportional quantities.

The correct answer is: 15


    Here, we have to find the missing number.
    Clearly, its constant of proportionality.
    To check constant of proportionality, we use y = kx
    6/25 = __/5 = 21/7 = 27/9 .
    Clearly, k = 3 and x = 5
    Y = 5 × 3 .
    Y = 15.
    Hence, the correct option is (b).

    When comparing two or more ratios, the constant of proportionality is a fixed number that indicates the rate at which ratios increase or decrease.
