If 24 over 15 = 4 over n , what is the value of 4 times n ?

Answer

Multiplying both sides of the equation 24 over 15 = 4 over n by 15 times n gives (15 times n) times (24 over 15) = (15 times n) times (4 over n) , which simplifies to 24 times n = (15) (4) = 60 . Dividing both sides of the equation 24 times n = 60 by gives (24 times n) over 6 = 60 over 6 , and so 4 times n = 10 .
