Question

1. white socks to brown socks

Answer 1

Answer:

Color of socks      Number of socks

white                          8

black                          6

blue                            4

brown                         5

Total socks =$8+6+4+5=23$

1. white socks to brown socks ratio = 8 : 5

2. blue socks to non blue socks

Non blue socks are = $8+6+5=19$

ratio is = 4 : 19

3. black socks to all of the socks ratio = 6 : 23

4. two ratios equivalent to the ratio in Exercise 1 that is 8 : 5

Any same integer number multiplied to both 8 and 5 will give same ratios.

Like : 32 : 20  (multiplied by 4)

56 : 35   (multiplied by 7)

Answer 2

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.
