Answer:

The value of y is 8.4375

Explanation:

Known :

  • y = 7.5
  • x = 2

Asked :

  • The value of y when x is 2.25

Solution :

2/7.5 = 2.25/y

Do a cross multiplication,

2/7.5 = 2.25/y

=> 20/75 = 2.25/y

=> 75 . 2.25 = 20y

=> 168.75 = 20y

Reverse the equation,

168.75 = 20y

=> 20y = 168.75

Find the value of y,

20y = 168.75

=> y = 8.4375

Conclusion :

y = 8.4375
