Question

Whats the fraction of 5 out of 20, 3 out of 20, 1 out of 20, and 9 out of 20?

Answer 1

You can think of the slash or "division symbol" as meaning "out of."

5/20 simplifies to 1/4
3/20 can't be further simplified, neither can the following
1/20
9/20

Answer 2

I'm assuming you mean to add them together? That would equal 1/2.
