One ratio is 30:40 since 15 times 2 is 30 and 20 times 2 is 40.
Find a number you can multiply by the bottom of the fraction to make it 10, 100, or 1000 and multiple both top and bottom by that number then write down just the top number putting the decimal point in the correct spot.

Answer:
The ratio is 6:2:1.
Step-by-step explanation:
Let's denote:
Blue counter b
Red counter r
Yellow counter y.
There is given
r=3b (three times more red as blue) [1]
and
b=2y (twice more blue as yellow.) [2]
Now, replacing [2] to [1] gives
3*2y=r
6y=r.
Hence, the ratio is 6:2:1, because r=6y and b=2y.
