Let the larger number be L and the lesser be 3/8 of it, i.e. (3/8)L. Their difference is
L − (3/8)L = (5/8)L = 4.2.
So L = 4.2 × (8/5) = 4.2 × 1.6 = 6.72.
The lesser number = (3/8)L = (3/8) × 6.72 = 2.52.
Answer: 2.52 (which is 63/25).
L − (3/8)L = (5/8)L = 4.2.
So L = 4.2 × (8/5) = 4.2 × 1.6 = 6.72.
The lesser number = (3/8)L = (3/8) × 6.72 = 2.52.
Answer: 2.52 (which is 63/25).
