Question

When ratio of two numbers is constant the variation is​

Answer 1

Answer:

The constant of variation in a direct variation is the constant (unchanged) ratio of two variable quantities. where k is the constant of variation . Example 1: If y varies directly as x and y=15 when x=24 , find x when y=25

Step-by-step explanation:

Answer 2

Answer:

Direct proportion

In direct variation, the ratio of two measurable quantities is constant. For example, if x and y are the two measurable quantities that are directly proportional to each other, then the direct proportion definition is Mathematically written as x ∝ y.
