b. The ratio of blue marbles to the total number of marbles.______​

Answer 1

Answer:

Look below

Step-by-step explanation:

A. Let's change the first ratio to...

6:2

  2:11

This means the ratio of red marbles to the total number of marbles is 6:11

B. We need to find out how many blue marbles there are. We already know there are 11 marbles in total. Now we need to find out how many red and green marbles there are...

2 green marbles + 6 red marbles = 8 marbles

11 marbles - 8 marbles = 3 blue marbles

So the ratio of blue marbles to the total number of marbles is 3:11
