How to do this question plz

6: 3: 1

Step-by-step explanation:

Let the number of blue, red, and green counters be b, r and g respectively.

"twice as many blue counters... as red counters"

➥b : r = 2 : 1

"3 times as many red counters... as green counters"

➥r : g = 3 : 1

Ensure that the number of parts for r is equal in both ratios. (Since the number of red counters does not change)

1st ratio→ r= 1 part

2nd ratio→ r= 3 parts

Thus, multiply the 1st ratio by 3 so that in both ratio, r= 3 parts.

b : r

= 2(3) : 1(3)

= 6 : 3

b : r= 6 : 3

r : g= 3 : 1

Now that r has equal parts in both ratios, we can combine the 2 ratios together.

b : r : g= 6 : 3 : 1

instagram is better than go there instead lol
