Suppose I have two cats
So, Ratio of length of cat to baby cat = 20/10
= 2/1
= 2 : 1
So, cat is twice as long as baby cat
Now, let’s take
So, Ratio of length of the cat to the Lion = 20/2
= 10/1
= 10 : 1
So, cat is 10 times as long as Lion?
WRONG
Here units are different
Cat’s length is in cm
Lion’s length is in m
So, we convert cm to m or cm
So,
Cat’s length = 20 cm
Lion’s length = 2 m
= 2 × 100 cm
= 200 cm
So, Ratio of cat’s length to lion’s length = 20/200
= 1/10
= 1 : 10
So, Cat’s length is 1/10 th of lion’s
So, we have to keep in mind units when forming ratio
