There are 750 students in a school. If the number of girls is 120 more than the boys, how many boys are there in the school?
b + b + 120 = 750
Solve for b.
there are 750 students in the whole school.but there is 120 more girls than boys.how many boys are there?
235
To find out how many boys are in the school, we need to set up an equation based on the given information.
Let's say the number of boys in the school is 'x'. According to the problem, the number of girls is 120 more than the boys. Therefore, the number of girls can be represented as 'x + 120'.
Now, we know that the total number of students in the school is 750. So, we can write the equation:
x + (x + 120) = 750
Simplifying the equation, we combine like terms:
2x + 120 = 750
Next, we isolate 'x' by subtracting 120 from both sides of the equation:
2x = 750 - 120
2x = 630
Dividing both sides of the equation by 2, we get:
x = 315
Therefore, there are 315 boys in the school.
