Question

There are 12481 people at a concert. 8906 of these people are adults. The rest of the people are children. (3)/(5) of the children are boys. Work out the number of girls at the concert.

Answer 1

After calculating the number of children at the concert (3,575) and determining that 3/5 of them are boys (2,145), we can find that there is a total of 1,430 girls at the concert.

Step-by-step explanation:

To determine the number of girls at the concert, we first need to calculate the number of children. Since there are 12,481 people at the concert, and 8,906 of them are adults, we can find the number of children by subtracting the number of adults from the total number of people.

12,481 (total people) - 8,906 (adults) = 3,575 (children)

Next, we know that 3/5 of the children are boys. To find out how many boys there are, we multiply the number of children by 3/5:

3,575 (children) × 3/5 = 2,145 (boys)

To find the number of girls, we subtract the number of boys from the total number of children:

3,575 (children) - 2,145 (boys) = 1,430 (girls)

Therefore, there are 1,430 girls at the concert.
