The book's Try It right after this example: same idea, new numbers. Only the answer is given.

Arnold’s SUV weighs about $4.3$ tons. Convert the weight to pounds.

How did it go?

	$3.2 tons$
Multiply the measurement to be converted by 1.	$3.2 tons \cdot 1$
Write 1 as a fraction relating tons and pounds.	$3.2 tons \cdot \frac{2000 lbs}{1 ton}$
Simplify.	$\frac{3.2 tons \cdot 2000 lbs}{1 ton}$
Multiply.	$6400 lbs$
	Ndula weighs almost 6,400 pounds.

	$3.2 tons$
Multiply the measurement to be converted by 1.	$3.2 tons \cdot 1$
