3) B. 4

4) A. 4

5) D. 16

Step-by-step explanation:

3) 6 : 8 = 3 : __

- 3 is half of 6, so we divide 8 by 2, which gives us 4

Ans: 6 : 8 = 3 : 4

4) 8 pails in 10 minutes = __ pails in 5 minutes

- 5 is half of 10, so the number of pails filled in 5 minutes will be half of 8, which gives us 4

Ans: 8 pails in 10 minutes = 4 pails in 5 minutes

5) 2 skilled workers for 4 ordinary laborers = 8 skilled workers for __ ordinary laborers

- 8 is 4 times more than 2, so there must be 4 times more ordinary laborers, which gives us 16

Ans: 2 skilled workers for 4 ordinary laborers = 8 skilled workers for 16 ordinary laborers
