Answer 1

Answer:

27 children

Step-by-step explanation:

Total passengers = 81

so, No. of males = 4/9 of 81 => 36 males

and now, no. of females = 2/9 of 81 => 18 females

and now, no of children => Total no. of passengers - no. of males + no. of females

81-(36+18) = 27 children

Answer 2

Answer:

$male = 81 \times (4 \div 9) = 9 \times 4 = 36$

$female = 81 \times 2 \div 9 = 9 \times 2 = 18$

$children = 81 - (36 + 18) = 81 - 54 = 27$
