there are 10 girls the ratio of girls to boys is 5:4 how many boys are there

5:4 = 10:8

To find the number of boys, we first need to determine the total number of children. Since the ratio of girls to boys is 5:4, we can consider the total number of parts as 5 + 4 = 9.

Next, we divide the total number of children (10) by the sum of the ratio parts (9) to find the value of one part.

10 / 9 = 1.1111...

Now, we can multiply the value of one part by the number of parts representing boys (4) to determine the number of boys.

1.1111... * 4 ≈ 4.44...

Since we cannot have a fraction of a child, we round the result to the nearest whole number.

Therefore, there are approximately 4 boys.
