Hector’s school is having a model rocket competition. To qualify, each rocket must weigh 4 pounds or less. Hector’s unpainted rocket weighs 62 ounces. What is the weight of the most paint he can use for his model rocket to qualify for entry?

• What weight does Hector need to convert?
The weight does Hector needed to convert is: Pound

• After Hector converts the weight, what does he need to do next?
After Hector converted the weight,
He had to find the amount of paint he can use for his model rocket to qualify for entry

Use a strip diagram to write an equation.

Step 1
Convert 4 pounds to ounces.

Step 2
Subtract the rocket’s weight from the total ounces a rocket can weigh to qualify.
64 – 62 = 2
So, the weight of the paint can be at most 2 ounces for Hector’s model rocket to qualify for entry.

How did you choose which operation to use to change from pounds to ounces? Explain.
We know that,
1 pound = 16 ounces
Now,
From the above relationship,
We can observe that
“Pound” is a larger unit and “Ounce” is a smaller unit
Now,
We know that,
When converting from a large quantity to a small quantity, we will multiply
Hence, from the above,
We can conclude that
The operation that used to change from pounds to ounces is: Multiplication

Example
The rocket boosters for a U.S. space shuttle weigh 1,292,000 pounds each when the shuttle is launched. How many tons does each rocket booster weigh?

Use mental math to convert pounds to tons.

Step 1
Decide which operation to use.
Since pounds are smaller than tons,
I need to divide the number of pounds by 2,000.

Step 2
Break 2,000 into two factors that are easy to divide by mentally.
2,000 = 1,000 × 2
Step 3
Divide 1,292,000 by the first factor. Then divide the quotient by the second factor.
1,292,000 ÷ 2,000 = 646
1,292 ÷ 2 = 646
So,
Each rocket booster weighs 646 tons when launched.
