There are 30 students in the class.

There are 4 more boys than girls in the class. What do I do to solve this?
The ratio is 4:1? Then what do with the 30? I am very confused.

this seems to be two questions

1st
b + g = 30
b = g + 4
substitute to find solution

2nd
4 + 1 = 5
30 / 5 = 6
30 - 6 = 24
there are 24 of one
and 6 of the other

To solve this problem, we can break it down into steps.

Step 1: Let's assume the number of girls in the class is x.
Step 2: Since the ratio of boys to girls is 4:1, the number of boys would be 4x.
Step 3: We know that the total number of students in the class is 30. Therefore, we can set up an equation:
x + 4x = 30
5x = 30

Step 4: To solve for x, divide both sides of the equation by 5:
x = 30 / 5
x = 6

So, there are 6 girls in the class (x = 6), and using the ratio, we can find the number of boys:
Boys = 4x = 4 * 6 = 24

Therefore, there are 6 girls and 24 boys in the class.
