Let X and Y be the number of red and blue circles respectively.
Then, by question,
X:Y=1:3
Now, if L be the number of circles needed to make the ratio 3:1, we get,
X:Y+L=3:1
or X/Y+L=3
or 1/3+L=3
or 3L=9
or L=3
Therefore the required number is 3.
Hope this will help you.

total number of red circles: total number of blue circles = 1:3
therefore number of red circles required to make red : blue = 3:1 =?
lets assume that there are 1 red circle and 3 blue circles
therefore number of red circles required
=> (x+1)/3 = 3/1
=> (x+1) = 3*3
=> x+1 = 9
=> x = 9 - 1
=> x = 8
Hence 8 more red circles required to make the ratio of red circles to the number of blue circles
I hope this helps. Please mark my answer as the branliest.
