Question

State whether the given statements are true or false:

(a) 12 : 18 = 28 : 56 

(b) 25 persons : 130 persons = 15 kg : 78 kg

Answer 1

(a) False, Because 

12:18 = 12/18 = 2/3 = 2:4

and 28:56 = 28/56 = 1/2 = 1:2

These are not equal.

(b) True, Because 

25 persons : 130 persons = 5: 26 

and 15 kg : 78 kg = 5: 26 

These are equal.
