Question
Are $30, 40$ and $45, 60$ in proportion$?$
✓
Answer
Since, Ratio of $30$ to $40 = \frac{30}{40} = 3 : 4.$
and Ratio of $45$ to $60 = \frac{45}{60} = 3 : 4.$
Such that $30 : 40 = 45 : 60$
Therefore, $30, 40, 45, 60$ are in proportion.
and Ratio of $45$ to $60 = \frac{45}{60} = 3 : 4.$
Such that $30 : 40 = 45 : 60$
Therefore, $30, 40, 45, 60$ are in proportion.
