Answer:

20:21

Step-by-step explanation:

Let's first start by converting each ratio so that the number of girls is the same

2:3

4:7

The least common multiple of 3 and 4 is 12 so...

8:12

  12:21

We add 8 and 12 to get the number of junior members...

8+12=20

Then we put it in a ratio with the amount of adult members...

20:21
