## Basic College Mathematics (10th Edition)

Determine how much weight has been removed from the truck by multiplying the current weight by $\frac{1}{10}$. $10,000 \times \frac{1}{10}$ There is common factor of 10, so you can use the rule of dividing by ten to easily see that the result of this formula is 1,000 pounds. If the weight has been reduced by 1000 pounds, you must subtract 1000 from the original weight to find the weight of the truck being tested. 10,000 - 1,000 = 9,000
