Question

There are 9 boys at a summer camp. The ratio

of boys to girls is 1 : 2. How many children are
at the summer camp in total?

Answer 1

Answer:The problem involves working out the total number of children at a summer camp, given that there are nine boys and the ratio of boys to girls is 1:2. This problem can be solved using simple ratio and proportion, and basic arithmetic skills.To understand the problem, one needs to know that a ratio is a way of comparing numbers. In this case, the ratio of boys to girl is 1:2, which means that for every one boy, there are two girls.To work out the total children at the summer camp, we need to start by setting up an equation involving the ratio. Let “x” be the number of girls, and “y” be the total number of children in the camp. We know that the ratio of boys to girls is 1:2, so the number of girls is twice the number of boys, that is, x=2(9)=18.Next, we add the number of boys to the total number of children to get y: y = 9 + 18 = 27. Therefore, there are 27 children total at the summer camp.To verify this result, we can check that the ratio of boys to girls is 1:2, which is the same as 9:18. Dividing both sides by 9, we get 1:2, which means that we have worked out the correct answer.In summary, the total number of children at the summer camp is 27. The problem requires the use of ratios as a comparison of numbers, and the use of basic arithmetic skills to calculate the total number of children at the summer camp.

Answer 2

Explanation:

If the ratio of boys to girls is 1:2, then for every 1 boy there are 2 girls.

Let's use "x" to represent the number of girls at the summer camp.

So, if there are 9 boys, then the total number of children at the summer camp can be represented as:

9 boys + 2x girls = total number of children

But we don't know what "x" is yet. We can use the ratio to find out.

Since the ratio of boys to girls is 1:2, we know that the number of boys is one-third of the total number of children.

So, we can set up the following equation:

9 = (1/3) * total number of children

To solve for the total number of children, we can multiply both sides by 3:

27 = total number of children

Now we know that there are 27 children at the summer camp in total.

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

27 - 9 = 18

Therefore, there are 18 girls at the summer camp and a total of 27 children.
