For an estimation, you could truncate to 1 decimal place and add: 9.3+5.1=14.4 To get a better estimate, add the second decimal place, if it is 5 or more, then round up the estimate. Second decimal place = 2+3=5 >=5, so round up 14.4 to 14.5.

Yep! Now you just neeed to round up until you get to the last decimal place. What do you think the 5 could be rounded to? up to 6, or down to stay at 5?

Good, now you have 14.46, what can that be rounded to?

Yes, but you do not need the 0 after the 5, since you want it to be only one decimal place. This way, you will have 14.5, your answer
