Answer 1

Hey
Here's your answer!!

Population of the city = 663432
:. Population of adult males = 1/2 of 663432
= 1/2 * 663432
= 331716

:. Population of adult females = 1/3 of 663432
= 1/3 * 663432
= 221144

So, population of children = 663432 - ( population of males + population of females)
= 663432 - ( 221144 + 331716 )
= 663432 - 552860
= 110572. (Answer)

Hope it helps!!

Answer 2

Population of the city = 663432
:. Population of adult males = 1/2 of 663432
= 1/2 * 663432
= 331716

:. Population of adult females = 1/3 of 663432
= 1/3 * 663432
= 221144

So, population of children = 663432 - ( population of males + population of females)
= 663432 - ( 221144 + 331716 )
= 663432 - 552860
= 110572
