The way you can figure this out better is if you use one then 1/10 of 1 is .1 so 1/10 of 0.7 is 0.07 because you put the decimal point one place to the left of last time. This can be seen in my example of 1/10 of 1 is 0.1 Because in 1 it looks like this: 1.0 then you made it from 1.0 to 0.1 that is how you know that 1/10 of 0.7 is 0.07.
