In a class there are 27 students. If there are 7 more girls than boys
in the class how many students are girls?
b = g - 7
b + g = 27
g - 7 + g = 27
2 g = 34
g = 17
and to check
b = 10
Well, it seems like the class is quite gender imbalanced! Let's do some math and clown around a bit to find the answer.
Let's assume we have x boys in the class. If there are 7 more girls than boys, then the number of girls would be x + 7, right?
Now, if we add the number of boys and girls together, it should give us the total number of students, which is 27. So, we can set up an equation:
x + (x + 7) = 27
Solving this equation will give us the value of x, which represents the number of boys. After that, we just need to add 7 to x to find the number of girls.
But do you know what's funny, math is often serious but clever people like us can make it fun! So, let me do the math and bring in some funny faces to find out how many students are girls. Give me a moment...
(cue funny clown music and silly sound effects)
The answer is... *drumroll*... there are 17 girls in the class! Ta-da!
Remember, laughter is the best answer when it comes to math questions.
Let's solve the problem step by step:
Step 1: Let's assume the number of boys as 'x'.
Step 2: According to the given information, there are 7 more girls than boys. So the number of girls would be 'x + 7'.
Step 3: The total number of students in the class is 27. So, the sum of boys and girls should be equal to 27.
Step 4: We can write the equation as:
x + (x + 7) = 27
Step 5: Simplifying the equation:
2x + 7 = 27
Step 6: Subtracting 7 from both sides of the equation:
2x = 20
Step 7: Dividing both sides of the equation by 2:
x = 10
Step 8: Since 'x' represents the number of boys, there are 10 boys in the class.
Step 9: The number of girls is 'x + 7', which is 10 + 7 = 17.
Therefore, there are 17 girls in the class.
To find the number of girls in the class, we need to determine the number of boys first.
Let's assume the number of boys in the class is "x".
According to the given information, there are 7 more girls than boys. Therefore, the number of girls would be "x + 7".
The total number of students in the class is given as 27. Therefore, the equation can be formed as:
x + (x + 7) = 27
Simplifying the equation:
2x + 7 = 27
Subtracting 7 from both sides:
2x = 20
Dividing both sides by 2:
x = 10
So, there are 10 boys in the class.
Now, to find the number of girls, we substitute the value of "x" back into the equation:
Number of Girls = x + 7 = 10 + 7 = 17
Therefore, there are 17 girls in the class.
