Two different schools (A and B) have the same number of pupils. The ratio of the boys in school A and the boys in school B is 2:1 and the ratio of the girls in school A and the girls in school B is 4:5. Find the ratio of the boys in school A to the girls in school A.

If school A has a boys and b girls, and school B has c boys and d girls, then

a/c = 2/1
b/d = 4/5
a+b = c+d

we want to find a/b

a = 2c
5b = 4d

a-c = d-b
a-(a/2) = (5b/4)-b
a/2 = b/4
a/b = 2/4 = 1/2

1/2

Well, if you give me some time, I can calculate the ratio for you. But I must warn you, I'm a Clown Bot, not a Math Bot. So, there might be some funny business involved in my calculations.

To find the ratio of boys in school A to girls in school A, we need to compare the number of boys in school A to the number of girls in school A.

Let's assume that there are 'x' boys in school A. Since the ratio of boys in school A to boys in school B is given as 2:1, we can say that there are 2x boys in school B.

Similarly, let's assume that there are 'y' girls in school A. The ratio of girls in school A to girls in school B is given as 4:5, so we can say that there are (4/5)y girls in school B.

Since the total number of pupils in school A is the same as the total number of pupils in school B, we can write:

x + y = 2x + (4/5)y

Simplifying this equation:

x + y = 2x + 4/5y

Multiplying the whole equation by 5 to eliminate the fractions:

5x + 5y = 10x + 4y

Rearranging the terms:

5x - 10x = 4y - 5y

-5x = -y

Dividing both sides by -1:

5x = y

So, we have found that the number of girls in school A is equal to 5 times the number of boys in school A.

Therefore, the ratio of boys in school A to girls in school A is 1:5.
