Part B: Fill in the Blank
Write the correct answer on each line.
1. A hallway is 60 feet long. That equals 20 yards.
One yard equals 3 feet, so to change feet into yards you divide by 3. 60 ÷ 3 = 20, so the hallway is 20 yards long.
2. A water bottle is about 25 centimeters tall.
A water bottle is about the length of a ruler. Centimeters are the right metric unit, since 25 cm is close to 10 inches, matching a standard bottle.
3. A bowling lane is about 60 feet long.
A bowling lane stretches from the foul line to the pins. That distance is 60 feet long, which is the right unit for something much bigger than a room.
4. Five rulers placed end to end measure 60 inches.
Each ruler is 12 inches long. Placing 5 rulers end to end gives 12 × 5 = 60 inches, which is the same as 5 feet.
5. A piece of yarn is 50 cm. Another piece is 50 cm. Together they are 1 meter.
Adding the yarn pieces gives 50 + 50 = 100 cm. Since 100 cm equals 1 meter, the two pieces together measure exactly 1 meter.
