Explain in words what mistake you made and how will correct it. in a group of 20 children, there were 8 girls. which is the ratio of girls to boys in simplest form?

Well first do 20 children minus 8 girls to find how many boys there are:

20-8=16

So there are 16 boys. Therefore we can write the ratio of girls to boys as:

8/16

Then we can simplify this ratio by dividing it by 8 to get:

1/2

So the answer is the ratio of girls to boys in the group in simplest form is 1/2.
