there are 80 students in math club. For every 5 girls, there are 3 boys. How many girls & boys in club.
Let x equal the number of girls.
Cross multiply and solve for x.
5/8 = x/80
8x = 400
x = 50
5+3=8
50+30=80
If for every 5 girls there are 3 boys, then for 50 girls there are 30 boys and 50+30=80 students in math club.
To find the number of girls and boys in the math club, we can set up a ratio based on the given information. According to the problem, for every 5 girls, there are 3 boys.
Let's assume the number of girls in the math club is represented by "5x", where "x" is a positive integer. Similarly, let's assume the number of boys is represented by "3x".
Since the total number of students in the math club is 80, we can set up an equation:
5x + 3x = 80
Combining like terms, we have:
8x = 80
To solve for x, we divide both sides of the equation by 8:
x = 80/8
x = 10
Now that we know that x = 10, we can substitute this value back into the expressions we assumed earlier:
Number of girls = 5x = 5 * 10 = 50
Number of boys = 3x = 3 * 10 = 30
Therefore, there are 50 girls and 30 boys in the math club.
