Question

the ratio of red circles and blue circles is 1:3 how many more red circles would be needed to make the ratio of red to blue 3:1

Answer 1

Answer:

the answer is 8 more red circles would be needed to make the ratio 3:1

Step-by-step explanation:

the ratio of red circle to blue circle is 1:3 and the new ratio is 3:1

let n no of red circles are added to make the ratio

3:1

then, 1+n:3=3:1

product of means =product of extreams

3x*3=1*(x+n)

9x=x+n

9x-x=n

n=8x

for x=1 then the ratio of red to blue is 1+8:3=9:3=3:1
