Question 394371
Look at the tenths place, which is underlined: 4.<u>2</u>91



Now look to the next digit to the right (which is in red): 4.2<font color=red>9</font>1



Since this number is at least 5 or more, this means that we're going to add 1 to the underlined digit above, which is 2. We ignore the rest of the digits to the right of our underlined digit. So we now have the number 4.3



So the answer is 4.3
