1. white socks to brown socks 2. blue socks to nonblue socks 3. black socks to all of the socks 4. find two ratios equivalent to the ratio in exercise 1. color of socks white black blue brown number of socks 8 64 5

8 White
6 Black
4 Blue
5 Brown
Total=8+6+4+5=23

1. White to brown = 8:5
2. Blue to non-blue =4:(23-4) = 4:19
3. Black to all = 6 : 23 
4. Ratios equivalent to Q1, 8:5
Multiply ratio by integer factors:
2(8:5)=16:10
3(8:5)=24:15
4(8:5)=32:20
etc.
