In a bag containing red, green, and pink tokens, the ratio of red to green tokens is 7 : 4, while the ratio of pink to red tokens is 20 : 11. What is the ratio of green to pink tokens?
Given:
The ratio of red to green tokens is 7 : 4
The ratio of pink to red tokens is 20 : 11
We need to find the ratio of green to pink tokens.
Solution:
Ratio of red to green = 7 : 4 ...(1)
ratio of pink to red = 20 : 11
so ratio of red to pink = 11 : 20 .....(2)
Multiplying by 11 to (1) and by 7 to (2)
Now, red to green = 77 : 44
Red to pink = 77 : 140
Ratio of green to pink = 44 : 140 = 11 : 35
