Ms Price has three times as many girls as boys in her classroom Ms Lippy has twice as many girls as boys. Ms. Price has 60 students, and Ms Lippy has 135 students. If the classes were combined into one, what would be the ratio of girls to boys?

x + 3x = 60 ; x boys ; x = 15

x + 2x = 135; x boys; x = 45

so combined total 60 boys & (45+90)girls

ratio is 135 : 60

Well, with Ms. Price, we know she has three times as many girls as boys. So if she has 60 students, we can divide that by 4 (3 girls + 1 boy) to get the number of boys. That means she would have 15 boys and 45 girls.

As for Ms. Lippy, she has twice as many girls as boys. So if she has 135 students, we can divide that by 3 (2 girls + 1 boy) to get the number of boys. That means she would have 45 boys and 90 girls.

Now, if we combine the two classes, we have a total of 75 boys (15 + 60) and 135 girls (45 + 90).

To find the ratio of girls to boys, we divide the number of girls by the number of boys: 135/75 = 9/5.

Therefore, the ratio of girls to boys in the combined classroom is 9:5.

To find the ratio of girls to boys when the classes are combined, we need to determine the total number of girls and boys in both classrooms.

Let's start by finding the number of girls and boys in Ms Price's classroom. We know that Ms Price has three times as many girls as boys, and her classroom has a total of 60 students.

Let the number of boys in Ms Price's classroom be x. Then, the number of girls in her classroom is 3x.

So, we have the equation x + 3x = 60, which gives us 4x = 60, and solving for x, we find x = 15.

Therefore, in Ms Price's classroom, there are 15 boys and 3(15) = 45 girls.

Now let's find the number of girls and boys in Ms Lippy's classroom. We know that Ms Lippy has twice as many girls as boys, and her classroom has a total of 135 students.

Let the number of boys in Ms Lippy’s classroom be y. Then, the number of girls in her classroom is 2y.

So, we have the equation y + 2y = 135, which gives us 3y = 135, and solving for y, we find y = 45.

Therefore, in Ms Lippy’s classroom, there are 45 boys and 2(45) = 90 girls.

To find the total number of boys and girls when the classes are combined, we add the number of boys and girls from both classrooms:

Total number of boys = 15 + 45 = 60 boys
Total number of girls = 45 + 90 = 135 girls

Now we can determine the ratio of girls to boys when the classes are combined:

Ratio of girls to boys = Total number of girls / Total number of boys
Ratio of girls to boys = 135 / 60
Ratio of girls to boys = 9/4

Therefore, the ratio of girls to boys when the classes are combined is 9:4.

To find the ratio of girls to boys when the classes are combined, we need to determine the number of girls and boys in both classes separately.

Let x be the number of boys in Ms Price's class. Since Ms Price has three times as many girls as boys, the number of girls in her class would be 3x.

Given that Ms Price has 60 students in total, the sum of the number of boys and girls in her class is x (boys) + 3x (girls) = 60 students.

Combining like terms, we can write this equation as:
x + 3x = 60
4x = 60
Divide both sides of the equation by 4:
x = 15

So, there are 15 boys in Ms Price's class and 3 * 15 = 45 girls.

Similarly, let y be the number of boys in Ms Lippy's class. Since Ms Lippy has twice as many girls as boys, the number of girls in her class would be 2y.

Given that Ms Lippy has 135 students in total, the sum of the number of boys and girls in her class is y (boys) + 2y (girls) = 135 students.

Combining like terms, we can write this equation as:
y + 2y = 135
3y = 135
Divide both sides of the equation by 3:
y = 45

So, there are 45 boys in Ms Lippy's class and 2 * 45 = 90 girls.

Now, we can find the total number of boys and girls when the classes are combined:
Total boys = 15 (from Ms Price) + 45 (from Ms Lippy) = 60 boys
Total girls = 45 (from Ms Price) + 90 (from Ms Lippy) = 135 girls

The ratio of girls to boys when the classes are combined is 135 girls to 60 boys, which can be simplified as 9 girls to 4 boys.
