Explanation:

Problem 1

Step1: Identify the operation

We need to find the total distance run by four students, each running 0.25 miles. So we multiply the distance per student by the number of students.
Expression: \( 4 \times 0.25 \)

Step2: Perform the multiplication

\( 4 \times 0.25 = 1 \)

Step1: Identify the operation

To find the total punch needed, we multiply the amount per student (0.5 liters) by the number of students (27).
Expression: \( 27 \times 0.5 \)

Step2: Perform the multiplication

\( 27 \times 0.5 = 13.5 \)

Step1: Identify the operation

To find the total candy needed, we multiply the amount per box (3.5 pounds) by the number of boxes (47).
Expression: \( 47 \times 3.5 \)

Step2: Perform the multiplication

\( 47 \times 3.5 = 164.5 \)? Wait, no, 473 = 141, 470.5=23.5, so 141 + 23.5 = 164.5? Wait, no, 3.547: 403.5=140, 73.5=24.5, so 140 + 24.5 = 164.5? Wait, the options have 164.5 as option C? Wait, the options are A.141.5, B.161.5, C.164.5, D.376. Wait, 3.547: let's calculate 473.5. 473 = 141, 470.5=23.5, so 141 + 23.5 = 164.5. So the correct answer is C? Wait, but let me check again. 3.5 47: 473 = 141, 470.5=23.5, 141+23.5=164.5. So option C is 164.5 pounds.
Wait, maybe I made a mistake earlier. Let's recalculate: 3.5 47. 473 = 141, 47*0.5 = 23.5, so 141 + 23.5 = 164.5. So the answer is C.

Answer:

D. 1 mile
