here is a little trick!

example: 1.23456

1.) start at the decimal.
2.) going right, count 10, 100, 1000, 10,000, 100,000 & so on (adding a zero each time)
3.) you are trying to round to the tenth place so you can stop counting at 10
~so the tenth place is this: 0._0000

4.) so the tenth place of my example is where it says 2.
5.) to round to it, you look at the number to the right of it; so the number to the right of 2 is 3.
6.) is that number (3) less than 5 or greater than 5. = 3 is less than 5
7.) so, you round the number down( this just means the # stays the same, so 2 stays as 2)
8.) so 1.23456 rounded to the nearest tenth = 1.2
