4. 2.932789 = 2.9
Explanation:
First thing: Where is the tenth spot?
3.568409
The 3 is staying so nothing is changing but look at the 3.56, the 5 is the tenth spot so now look at the hundredth spot 3.56 If the hundredth spot is above 5 then the 3.5 becomes a number higher
So now it is 3.6
On 2.932789 the hundredth spot is 3 which is less than 5
So it will stay 2.9
Hope this helps, don't worry everyone forgets things once in a while!
