In a class, 18 children are girls.
A quarter of the children are boys.
Altogether, how many children are there in the class?
if 1/4 are boys, the 18 girls make up 3/4 of the class.
18 = 3/4 * 24
To find the total number of children in the class, you need to add the number of girls and boys together.
First, we know that there are 18 girls in the class.
Next, we are told that a quarter of the children are boys. "A quarter" means one-fourth, which can be represented as 1/4. Since we don't know the total number of children yet, we can represent it as "x". Then, we can write the equation: (1/4)x = number of boys.
To find the total number of children, we need to combine the number of girls and boys. We can write the equation as: 18 + (1/4)x = total number of children.
To solve this equation, we need to find the value of "x". We can do this by multiplying both sides of the equation by 4 to eliminate the fraction: 4 * (18 + (1/4)x) = 4 * (total number of children).
Using the distributive property, we get: 72 + x = 4 * (total number of children).
Simplifying further, we have: 72 + x = 4 * total number of children.
To isolate the total number of children, we subtract 72 from both sides: x = 4 * total number of children - 72.
Now we have an equation to find the value of "x". However, we don't have enough information to solve for "x" since we don't know the exact number of boys or the total number of children in the class.
Therefore, to determine the total number of children in the class, we need more information such as the number of boys or the specific value of "x".
number is the whole class ---- x
number of boys = x-18
or
number of boys = (1/4)x
x/4 = x-18
times 4
x = 4x - 72
-3x=-72
x = 24
