Question 2.
Sarabi uses a table to find the number of pounds in 3 tons. Which describes her error? A. Sarabi thinks there are 1,000 pounds in a ton instead of 1,200.
B. Sarabi thinks there are 1,200 pounds in a ton instead of 2,000.
C. Sarabi adds the same amount instead of multiplying.
D. Sarabi multiplies by the same amount instead of adding. We know that 1 ton is equal to 2,000 pounds.
3 tons is equal to 6,000 pounds.
So, Option B describes her error.

Question 3.
Use Tools Write the correct letter to match the equivalent lengths. Tell what strategy or tool you will use to solve the problem, explain your choice, and then find the answers.  Explanation:
We know that 1 yard is equal to 3 feet.
3 yards = 3 x 3 = 9 feet
So, 3 yards is equal to 9 feet. So, write the letter B in front of 3 yards.
We know that 1 yard is equal to 36 inches.
2 yards = 2 x 36 = 72 inches
So, 72 inches is equal to 2 yards. So, write the letter C in front of 72 inches.
We know that 1 feet is equal to 12 inches.
3 feet = 3 x 12 = 36 inches
So, 3 feet is equal to 36 inches. So, write the letter A in front of 3 feet.

Question 4.
Gibbons, a type of ape, swing from branch to branch. A researcher measures the distance of nine gibbon swings. How much farther is the longest swing than the shortest swing? The measurements are given. Draw a line plot of the data. The longest swing is 2 1/2.
The shortest swing is 1/2.
Subtract shortest swing from longest swing the difference is 2 yards.
2 1/2 – 1/2 = 2 yards
2 yards farther is the longest swing than the shortest swing.
