A)
1
8
B)
1
12
C)
1
18
D)
1
24

Answer 1

1/12mi or B

Explanation:

so we want to divide 1/3 mile into 4 parts (1 for each volunteer)

1/3 divided by 4 is 1/3 times 1/4 or 1/(3*4)=1/12

answe ris 1/12 or B

Answer 2

B.
`\frac { 1 } { 1 2 }`

Explanation:

We are given that 4 volunteers removed the litter from
`(1)/(3)` of a mile of state highway equally.

We are to find the fraction of a mile each volunteer cleans.

For that, we simply will divide the length of highway cleaned by the total number of volunteers.

Fraction of mile cleaned by each volunteer =
`\frac { \frac { 1 } { 3 } } { 4 }  = \frac { 1 } { 1 2 }`

So the correct answer option is B.
`\frac { 1 } { 1 2 }`.
