A bag contains 60 marbles that are red, blue, and green. The ratio of red to blue marbles is 13:3, and the ratio of blue to green marbles is 3:4, If 3 marbles are removed and replaced with 3 green marbles, what will be the new ratio of red to green marbles?

I'm Confused can someone help?

Answer:

3 marbles of what are removed (green red or blue)

Explanation:

60 marbles=red+blue+green

red:blue

(13 : 3)

blue:green

( 3 : 4)

red:blue:green

13 : 3 : 4

13/20×60=39 red marbles

3/20 × 60=9 blue marbles

4/20× 60= 12 green marbles

60-3

=57

x-3
