Answer: Yes they are in the same proportion
The ratio 2:6 reduces fully to 1:3 after dividing both parts by 2
2/2 = 1
6/2 = 3
It's similar to saying 2/6 = 1/3
Also, the ratio 7:21 reduces to 1:3 because we divide both parts by 7
7/7 = 1
21/7 = 3
Therefore, 2:6 and 7:21 are effectively the same ratio.
