Answer 1

I have no idea 3 pounds?

Answer 2

Answer:

$14\frac{21}{40}$ pounds.

Step-by-step explanation:

We have been given that an object that weighs 1 pound on Earth weighs only 0.17 pound on the moon. Zack's dog weighs 17 1/2 pounds on earth.

First of all, we will find weight of Zack's dog on moon as:

$17\frac{1}{2}\times 0.17$      

$\frac{35}{2}\times \frac{0.17*100}{100}$      

$\frac{35}{2}\times \frac{17}{100}$  

$\frac{7}{2}\times \frac{17}{20}$      

$\frac{119}{40}$

Now, we will subtract the weight on Zack's dog on moon from its weight on earth as:      

$17\frac{1}{2}-\frac{119}{40}$

$\frac{35}{2}-\frac{119}{40}$

$\frac{35*20}{2*20}-\frac{119}{40}$

$\frac{700}{40}-\frac{119}{40}$

$\frac{700-119}{40}$

$\frac{581}{40}$

$14\frac{21}{40}$

Therefore, the weight of Zack's dog is $14\frac{21}{40}$ pounds more on earth than moon.
