Question

q is directly proportional to r, q has a value of 24 when r = 16. Find the value of q when r is 12.

Answer 1

Answer:

18

Step-by-step explanation:

directly proportional

so

q/r is constant

q=24

r=16

q/r=24/16

second case =q/12 we have to find q

so 24/16=q/12

q=24x12/16

288/16

=q that is =18

CHECKING

to check simplify 24/16 on simplifying we get with 4

6/4 then with 2 we get 3/2

then other 12/18

on simplifying by 6 we get 3/2 so correct
