There are 12 marbles in a bag 1 black to orange for green and 5 yellow what fraction of the marbles are yellow you all for me

Hello!

There are two parts of a fraction. The top part is called the 'numerator' and the bottom part is the 'denominator'.

The numerator is how many of something there is, and the denominator is the total amount of something, or, 1 whole.

In this case, 5 would be the numerator because there are 5 YELLOW marbles, and 12 would be the denominator because that is the total amount of marbles.

So, your answer is:

5/12 of the marbles are yellow.
