What is 2.24 rounded to the nearest tenth?

The number 2.24 rounded to the nearest tenth is 2.2
The nearest tenth means 1 decimal place, so you need to look at the number 4.
0-4 = rounding down or keeping it as it is
5-9 = rounding up

So because 4 means keeping the next value as it is. 

2.2 ;) caus the hundredth is not over 5 so there for the answer is 2.2 
and im only in fifth grade

I’m not absolutely sure but i think it’s 7x6x5x4x3x2=5040 because as the first character you can take any of the 7 given then you are left with 5 then 6 then 4 etc.
