Question

Do the ratios 25 cm 2 m and 225 seconds to 30 minutes form a proportion ?

Answer 1

The ratios 25 cm 2 m and 225 seconds to 30 minutes form a proportion

2m expressed in m as,

200cm

So, the ratio of 25cm to 200cm is:

25/200 = 1/8

which is 1:8

Second ratio is between 225s to 30minutes.

1 minute = 60s

So, 30 minutes = 1800s

So, the ratio of 225s to 1800s

225/1800 = 1/8

which is 1:8

Since the two ratios are equal, so they form a proportion.
