A concrete truck loaded with concrete weighs up to 21 tons.

About how many pounds does the loaded truck weigh?

The loaded truck weighs pounds.

42,000 pounds

Step-by-step explanation:

Let's make a proportion

There are 2,000 pounds in 1 ton

2000 pounds is to 1 ton, and x pounds is to 21 tons

2000/1=x/21

Multiply both sides by 21 to "reverse" the division being done to x

21*(2000/1)=(x/21)*21

42,000=x

The loaded truck weighs 42,000 pounds
