Helping students with homework can be easier with examples rather than rules.

10 times as much as  vs. 1/10 of  can be clarified by using better numbers:

so we chose 6 as our better number
6   is 10 times as much as 0.6 and 1/10 of 60

Now we know how to answer each column by comparing it to our easy example of 6!!

CCSS.MATH.PRACTICE.MP7 Look for and make use of structure.
Once we see how 6 worked with 0.6 and 60, we can extend that idea to the harder decimal numbers given.
