Question

Round four point seven six to one decimal place

Answer 1

4.76 rounded to one decimal place is 4.8

Look at the decimal place you want to round (the 7, since it is the one decimal place).
Then look at the next digit (the 6). If it is 5 or greater, round up. Otherwise, round down.
You round up the 7 up because 6 is 5 or greater.
So you get the answer 4.8
