Given: (4+5)/5 = 4/(5y)
Simplify left side: 9/5 = 4/(5y)
Multiply both sides by 5y to get: 9y = 4
Divide both sides by 9 to get: y = 4/9
Compare:
Quantity A: 8/(9y)
Quantity B: 2
Replace y with 4/9 to get:
Quantity A: 8/[9(4/9)]
Quantity B: 2
Simplify denominator:
Quantity A: 8/(36/9)
Quantity B: 2
Simplify:
Quantity A: (8)(9/36)
Quantity B: 2
Evaluate:
Quantity A: 72/36 = 2
Quantity B: 2

Given: (4+5)/9 = 4/5y
Simplify left side: 9/9 = 4/5y
Simplify left side: 1 = 4/5y
Multiply both sides by y to get: y = 4/5
Compare:
Quantity A: 8/(9y)
Quantity B: 2
Replace y with 4/5 to get:
Quantity A: 8/[9(4/5)]
Quantity B: 2
Simplify denominator:
Quantity A: 8/(36/5)
Quantity B: 2
Simplify:
Quantity A: (8)(5/36)
Quantity B: 2
Evaluate:
Quantity A: 40/36 = 10/9 = 1 1/9
Quantity B: 2
