A chef makes 1 \(\frac{1}{2}\) gallons of soup in a large pot. How many 1-cup servings can the chef get from this large pot of soup?
_____ 1-cup servings
Answer: 24 1-cup servings
Explanation:
A chef makes 1 \(\frac{1}{2}\) gallons of soup in a large pot.

How many students compared times?
______ students
Answer: 8
Explanation:
Number of students spent \(\frac{1}{6}\) of an hour on school bus = 2
Number of students spent \(\frac{2}{6}\) of an hour on school bus = 1
Number of students spent \(\frac{3}{6}\) of an hour on school bus = 4
Number of students spent \(\frac{4}{6}\) of an hour on school bus = 1
Total number of students = 2 + 1 + 4 + 1 = 8 students
Question 3.
What is the difference between the longest time and shortest time students spent riding the bus?
\(\frac{□}{□}\) hour
Answer: \(\frac{3}{6}\)
Explanation:
Longest time is \(\frac{4}{6}\) and shortest time is \(\frac{1}{6}\)

Question 7.
Write the symbol that compares the weights correctly.
128 ounces ____ 8 pounds
8,000 pounds ____ 3 tons
Answer:
i. 128 ounces ____ 8 pounds
1 pound = 16ounces
8 pounds = 8 × 16 ounces = 128 ounces
Thus 128 ounces = 8 pounds
ii. 8,000 pounds ____ 3 tons
1 ton = 2000 pounds

= 2 (34 in. + 20 in.)
= 108 in.
Question 6.
P = _____ feet
Answer: 464 feet
Explanation:
The side of the square is 116 feet
The perimeter of the square = 4a
= 4 × 116 feet = 464 feet.
Thus the perimeter of the square is 464 feet.
Question 7.
P = _____ meters
Answer: 126 meters
Explanation:
The length of the rectangle = 42 meters
The width of the rectangle = 21 meters
The formula for the perimeter of the rectangle is 2 (l + w)
= 2 (42 m + 21 m) = 2 (63 m) = 126 meters
Therefore the perimeter of the above rectangle is 126 meters.
Question 8.
Robert wants to put lights around the edge of his yard. The yard is 40 feet long and 23 feet wide. How many yards of lights does he need?
