Determine if the following ratio form a proportion
200 mL : 2.5 L :: ₹ 4 : ₹ 50

The correct answer is Yes

200 mL : 2.5 L :: ₹ 4 : ₹ 50

200 mL : 2.5 L = 200 mL : 2500 mL

⇒ $\dfrac{200}{2500}$ = $\dfrac{2}{25}$


₹ 4 : ₹ 50

⇒ ₹ 4 : ₹ 50 = $\dfrac{4}{50}$ = $\dfrac{2}{25}$


∴ 200 mL : 2.5 L :: ₹ 4 : ₹50 are in proportion.
