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.
