Question

Determine if the following ratios form a proportion. Also, write the middle terms and extreme terms where the ratios form a proportion.

$25cm:1mand₹40:₹160$

Answer 1

As we have

$25cm:1mand₹40:₹160$

On taking the ratio of given sets we get

$$\begin{gathered} 25cm=\frac{25}{100}m=0.25m\left[\because 1cm=\frac{1}{100}m\right] \\ Now, \\ \frac{0.25}{1}=\frac{1}{4} \\ Also,\frac{₹40}{₹160}=\frac{1}{4} \end{gathered}$$

Yes, the given set of numbers are in a proportion as We can say $25cm:1m=₹40:₹160$

Middle terms are $1m,₹40$

Extreme terms are $25cm,₹160$
