Step-by-step explanation:
proportionally, a : b = 3 : 4, then, explicitly, what ratio has a to b?
Answer. The proportion implies the ratio of a to b, but it does not state that ratio explicitly. What ratio has 3 to 4? 3 is three fourths of 4. Explicitly, then, that is the ratio of a to b. a is three fourths of b.
Proportions imply ratios.
