" For every 1 girl, there are 2 boys " . This indicates a fraction.
The correct option is B False.
Since, a fraction is part of whole.
ex: 3 mangoes out of 4 mangoes represented as 34.
But in given statement is, " For every 1 girl, there are 2 boys " as 1:2.
1:2 indicates a ratio not fraction.
So, answer is False.
