The ratio of girls to boys in the school is 3 to 1 if there is a total of 400 students, how many are boys? The answer must be a whole number . (1 point)
AAAaannndd the bot gets it wrong yet again!
300 girls, 100 boys
To solve this question, we need to determine the ratio of girls to boys.
The ratio of girls to boys is given as 3 to 1. This means that for every 3 girls, there is 1 boy.
If the total number of students in the school is 400, we can set up the following equation:
3x + 1x = 400
Combining like terms, we have:
4x = 400
To solve for x, divide both sides of the equation by 4:
x = 400 / 4 = 100
Since x represents the number of boys, we can conclude that there are 100 boys in the school.
To find the number of boys in the school, we can use the given ratio and total number of students.
The ratio of girls to boys is 3 to 1, which means that for every 3 girls, there is 1 boy.
Let's represent the unknown number of boys as x. Since the ratio is 3 to 1, the number of girls can be calculated as 3x.
According to the problem, the total number of students is 400. So the equation becomes:
3x + x = 400
Combining like terms:
4x = 400
To solve for x, we need to isolate it on one side of the equation. Divide both sides of the equation by 4:
4x/4 = 400/4
Simplifying:
x = 100
Therefore, there are 100 boys in the school.
