Whats 1.625 rounded to the nearest tenth??!

As you're rounding the to nearest tenth, this means you've got to round the 2nd digit.
As the last two digits are 0.025, they round up (as anything including and over 5 rounds up),
Therefore, they round to 3, meaning that the 2nd digit will not round up. 
Thus, 1.625 rounded to the nearest tenth is 1.6 
Hope this helps :)
