We can solve this question quickly by using matching operations.

Quantity A: 4.2701 + (2.291/2) - 5.6446
Quantity B: 1.111 - 5.6446 + 4.2701

Subtract 4.2701 from both quantities to get:
Quantity A: (2.291/2) - 5.6446
Quantity B: 1.111 - 5.6446

Add 5.6446 to both quantities to get:
Quantity A: 2.291/2
Quantity B: 1.111

Multiply both quantities by 2 to get:
Quantity A: 2.291
Quantity B: 2.222
