A bag of marbles has 15 blue, 25 red and 5 green. Write and simplify the ratio of blue to red to green marble.

Answer 1

Hi Jalina,

Remember that a ratio = part/whole

You have 15 + 25 + 5 marbles total, so Blue Marbles = 15/45, Red Marbles = 25/45 etc.

So the ratio of Blue/Red...put the Blue Ratio over the Red Ratio simplify.
