I have no idea why they say that. :>0 Maybe they're comparing one object's 50% is less than another's 20%. Sorry, I've never heard this.
Since it’s a negative exponent you move the decimal backwards instead of forwards. So, the answer would be .00000000000632 and .000095

Answer:
![1\frac{19}{30}](https://tex.z-dn.net/?f=1%5Cfrac%7B19%7D%7B30%7D)
Step-by-step explanation:
To operate between mixed numbers is always better to write then in fraction form first (as improper fractions), and then operate using the rules to combine fractions.
For the first mixed number :
![4\frac{5}{6} = 4+\frac{5}{6} =\frac{24}{6} +\frac{5}{6}=\frac{29}{6}](https://tex.z-dn.net/?f=4%5Cfrac%7B5%7D%7B6%7D%20%3D%204%2B%5Cfrac%7B5%7D%7B6%7D%20%3D%5Cfrac%7B24%7D%7B6%7D%20%2B%5Cfrac%7B5%7D%7B6%7D%3D%5Cfrac%7B29%7D%7B6%7D)
For the second mixed number:
![3\frac{1}{5} =3+\frac{1}{5}=\frac{15}{5}+\frac{1}{5}=\frac{16}{5}](https://tex.z-dn.net/?f=3%5Cfrac%7B1%7D%7B5%7D%20%3D3%2B%5Cfrac%7B1%7D%7B5%7D%3D%5Cfrac%7B15%7D%7B5%7D%2B%5Cfrac%7B1%7D%7B5%7D%3D%5Cfrac%7B16%7D%7B5%7D)
So now we have to subtract these two fractions, so we need to write them with the same common denominator (6 x 5 = 30):
![\frac{29}{6}-\frac{16}{5}=\frac{145}{30} -\frac{96}{30}=\frac{49}{30}](https://tex.z-dn.net/?f=%5Cfrac%7B29%7D%7B6%7D-%5Cfrac%7B16%7D%7B5%7D%3D%5Cfrac%7B145%7D%7B30%7D%20-%5Cfrac%7B96%7D%7B30%7D%3D%5Cfrac%7B49%7D%7B30%7D)
and finally we write the obtained answer in mixed number form:
![\frac{49}{30} =1+\frac{19}{30} =1\frac{19}{30}](https://tex.z-dn.net/?f=%5Cfrac%7B49%7D%7B30%7D%20%3D1%2B%5Cfrac%7B19%7D%7B30%7D%20%3D1%5Cfrac%7B19%7D%7B30%7D)
The answer is B. First divide the numerator by the denominator which gives you 1 with a remainder of 10. The 1 is the whole number. The remainder of 10 will be the new numerator and the 17 as the dominator since it stays the same. And there is your answer:)
