Hello there! Here are your answers:
1. 9.631 hundredths, 0.03
2. 96.31 tenths, 0.3
It's place is how far away it is from the decimal point. If it's the first number after the decimal point, it's in the tenths, if it's the second number it's in the hundredths, if it's the third, it's the thousandths, etc...
In the first equation, the 3 is two places after the decimal, making it hundredths.
In the second equation, the 3 is one place after the decimal, making it tenths.
Now to find the value. This is the easy part.
Just look at the number and remove the other decimal places.
So, for 9.631 if you remove the 9, 6, and 1 and replace them with zeros you get 0.030, which you can simplify to 0.03.
For 96.31, if you remove the 9, 6, and 1 and replace them with zeros you get 00.30, which you can simplify to 0.3.
Hope this helps, and have a great day!
