Question

There is direct variation between m and n. When m = 25, n=15. Find the constant of proportionality and write the equation for this variation.

Answer 1

Answer:

The constant of proportionality is 5/3

The equation is m = (5/3)n

Step-by-step explanation:

Since m and n have direct variation

Therefore

m = kn   ............ (1)

Where k is the constant of proportionality

Given in the question

When m = 25, n = 15

Therefore putting it in the eq (1)

25 = k × 15

or k = 25/15 = 5/3

Therefore, the constant of proportionality is 5/3

The equation is m = (5/3)n
