What is the answer to round 209.971 to the nearest tenth?

Answer 1

209.971

Note that:

• 9 is in the tenths digit
• Next to that digit, 7 is in the hundredths digit

Since 7 is at least 5, we round up the value to obtain:

210.0

If the adjacent digit is not at least 5 i.e. 0,1,2,3,4, then we round down the value.
