Answer:
none of them
Step-by-step explanation:
Remark
The short answer is you multiply 0.6 times the cm/s to get m/min.
Solve
Though you didn't ask for it, here's the way it is done. Notice that each set of brackets cancels the units of a set of brackets to the left of the set of brackets you are observing. This is called unit analysis. The answer is given below.
![\frac{18 cm}{sec} *[\frac{60 cm}{1 min}] * [\frac{1 m}{100 cm}] = 18*0.6\frac{m}{min}=10.8\frac{m}{min}](https://tex.z-dn.net/?f=%20%5Cfrac%7B18%20cm%7D%7Bsec%7D%20%2A%5B%5Cfrac%7B60%20cm%7D%7B1%20min%7D%5D%20%2A%20%5B%5Cfrac%7B1%20m%7D%7B100%20cm%7D%5D%20%3D%2018%2A0.6%5Cfrac%7Bm%7D%7Bmin%7D%3D10.8%5Cfrac%7Bm%7D%7Bmin%7D)
I think it would be layer 4
Answer:
-5 and -10
Step-by-step explanation:
Answer:

Step-by-step explanation:

When converting mixed numbers (such as the one above), to improper fractions, we must first multiply the whole number by the denominator:

Then, add the numerator the the product:

Now, put the sum over the denominator to get your solution:

-
To check your work, you can convert the improper fraction to a mixed number to make sure you will end up with
.
Divide
into
:
with a remainder of 
Put the remainder over the denominator:

Therefore, our solution is correct!
