=> 384 ounces.
Question 2.
A school bus weighs 17,400 pounds. A truck 1 weighs 7\(\frac{1}{2}\) tons. How much heavier is the bus in pounds?
Answer:
2400 pounds more heavier is the bus in pounds.
Explanation:
Number of pounds a school bus weighs = 17,400.
Number of tons a truck 1 weighs = 7\(\frac{1}{2}\) tons = 7.5 tons.
Conversion:
1 ton = 2000 pounds.
=> 17400 pounds = 17400 ÷ 2000
=> 8.7 tons.
Difference:
Number of tons a school bus weighs – Number of tons a truck 1 weighs
= 8.7 – 7.5
= 1.2 tons.
Conversion:
1 ton = 2000 pounds.
=> 1.2 tons = 2000 × 1.2
=> 2400 pounds.
Question 3.
Mona has a large straw basket that can hold up to 25 lbs without breaking. She wants to put 220 oz of apples and 160 oz of bananas into the basket. Can the basket hold the apples and bananas without breaking? How do you know?
Answer:
Yes, basket can hold apples and bananas because there weight is less than the basket weight.
Explanation:
Number of pounds Mona large straw basket that can hold without breaking = 25.
Number of ounces of apples she wants to put into the basket = 220.
Number of ounces of bananas she wants to put into the basket = 160.
Total number of ounces of fruits she wants to put into the basket = Number of ounces of apples she wants to put into the basket + Number of ounces of bananas she wants to put into the basket
= 220 + 160
= 380.
Conversion:
1 pound = 16 ounces.
=> 380 ounces = 380 ÷ 16
=> 23.75 pounds.

=> 16000 pounds.
Question 5.
Ms. Hoy finds two boulders at an archaeological site. One boulder weighs 3.2 T and the other weighs 1.8 T. What is the sum of the weights of the boulders in pounds?
Answer:
10000 pounds is the sum of the weights of the boulders in pounds.
Explanation:
Number of tons One boulder weighs = 3.2.
Number of tons other boulder weighs = 1.8.
Total number of tons both boulder weighs = Number of tons One boulder weighs + Number of tons other boulder weighs
= 3.2 + 1.8
= 5.
Conversion:
1 ton = 2000 pounds.
=> 5 tons = 2000 × 5
=> 10000 pounds.
Question 6.
Three people buy fish at a store. Mr. Jones buys 1.3 pounds, Ms. Smith buys 1.5 pounds, and Mr. Lee buys 2 pounds. How many ounces of fish do they buy in all?
Answer:
76.8 ounces of fish do they buy in all.
Explanation:
Number of pounds fish at a store Mr. Jones buys = 1.3.
Number of pounds fish at a store Ms. Smith buys = 1.5.
Number of pounds fish at a store Mr. Lee buys = 2.
Total number of pounds they all buy = Number of pounds fish at a store Mr. Jones buys + Number of pounds fish at a store Ms. Smith buys + Number of pounds fish at a store Mr. Lee buys
= 1.3 + 1.5 + 2
= 2.8 + 2
= 4.8.
Conversion:
1 pound = 16 ounces.
=> 4.8 pounds = 16 × 4.8
=> 76.8 ounces.
