b. 12*1/4

c. 12+1/4*12

d. 12 (1 + 1/4)

e. 12*3/4

f. 12*5/4

c., d., f

Step-by-step explanation:

"elana walked 12 miles"

That is 12.

"then she walked 1/4 that distance"

That is 1/4 of 12 miles, so it is 1/4 * 12

She walked altogether

12 + 1/4 * 12 = 12 + 3 = 15

She walked altogether 15 miles.

a. 12+1/4 = 12.25 which is not 15

b. 12*1/4 = 3 which is not 15

c. 12+1/4*12 = 12 + 3 = 15 which is correct

d. 12 (1 + 1/4) = 12 (1.25) = 15 which is correct

e. 12*3/4 = 9 which is not 15

f. 12*5/4 = 15 which is correct

Answer: c., d., f
