Question

What is the answer for. What is hg = 45g

Answer 1

To solve hg = 45g

Apply Multiplication Property of Equality which is to multiply both sides of the equation with 1/g.
  
  hg (1/g) = 45g (1/g)
               h = 45

Or you can divide both sides with the equation with g.
      
   hg / g = 45g / g

You can cancel g to both sides.
Then, 
               h = 45
