Question

At Edward's school, 8 out of every 10 students are girls. There are a total of 1005 at the school. What is the number of girls at Edward's school?

Answer 1

the best way to do this is to set up a proportion

8 x
--- = ---
10 1005

then cross multiply and divide

8 times 1005=8040/10=804

there are 804 girls at the school
