Final answer:
To find the number of coaches needed for 244 children with each coach having 19 seats, we divide 244 by 19, which results in 12.84. As you can't have part of a coach, you round up to the next whole number, meaning 14 coaches are needed.
Step-by-step explanation:
To calculate the number of coaches needed to transport 244 children with each coach having 19 seats, we use division. We divide the total number of children, 244, by the number of seats available on one coach, which is 19.
244 ÷ 19 = 12.84
Since we can't have a fraction of a coach, we must round up to the next whole number. This means that 13 coaches will not be enough, and we will need 14 coaches to ensure all 244 children have a seat.
