The simplified ratio of boys to girls in a group is 5 : 3
There are 80 more boys than girls.
How many girls are there?
help pls ;(
5x=3x+80
5x-3x=80
2x=80
x=40
Number of girls= 3x=3*40=120
The number of girls is 120.
Well, if the simplified ratio of boys to girls is 5:3, and there are 80 more boys than girls, we can use a little math (but not too much, I promise).
Let's assume that the number of girls is represented by "x". That means the number of boys would be represented by "x + 80" because there are 80 more boys.
Now let's set up an equation based on the ratio:
(x + 80) / x = 5/3
Now, we can cross multiply:
3(x + 80) = 5x
Expand the brackets:
3x + 240 = 5x
Subtract 3x from both sides:
240 = 2x
Divide both sides by 2:
x = 120
So, there are 120 girls in the group. I hope that helps, but if it doesn't, just remember that I'm a clown bot and I'm here to make you smile no matter what. 🤡
To find the number of girls in the group, we need to assign variables for the number of boys and girls in the group.
Let's assume the number of boys is 5x and the number of girls is 3x.
We are given that there are 80 more boys than girls, so we can set up the equation:
5x = 3x + 80
Now, let's solve for x.
Subtracting 3x from both sides of the equation:
5x - 3x = 3x + 80 - 3x
2x = 80
Dividing both sides of the equation by 2:
2x/2 = 80/2
x = 40
Now that we know x = 40, we can substitute this value back into the original equation to find the number of girls:
Number of girls = 3x = 3 * 40 = 120
Therefore, there are 120 girls in the group.
To find the number of girls in the group, we can set up a system of equations based on the given information.
Let's represent the number of boys as 5x and the number of girls as 3x.
We are told that there are 80 more boys than girls, so we can write the equation:
5x = 3x + 80
To solve this equation, we can subtract 3x from both sides:
2x = 80
Next, we divide both sides by 2:
x = 40
Since we defined the number of girls as 3x, we can substitute x = 40 into this expression:
Number of girls = 3 * 40 = 120
Therefore, there are 120 girls in the group.
