Final answer:
The correct answer is option 3. To complete the equations with powers of 10, the missing terms can be determined by comparing the given numbers to the desired results. The missing term for each equation is 10 raised to the power of the difference between the given number and the desired result. The resulting equations are 720,800 / 10^-4 = 7.208, 720,800 / 10^-2 = 72.08, and 720,800 / 10^-1 = 720.8.
Step-by-step explanation:
To complete the equations with powers of 10, we can determine the missing terms by comparing the given numbers to the desired results.
For the equation 720,800 / ? = 7.208, we can see that the result is 7.208 times smaller than the given number. Therefore, the missing term should be 10-4, resulting in 720,800 / 10-4 = 7.208.
Similarly, for the equation 720,800 / ? = 72.08, the result is 72.08 times smaller than the given number. Therefore, the missing term should be 10-2, resulting in 720,800 / 10-2 = 72.08.
Lastly, for the equation 720,800 / ? = 720.8, the result is 720.8 times smaller than the given number. Therefore, the missing term should be 10-1, resulting in 720,800 / 10-1 = 720.8.
