What is 8.54 rounded to the nearest tenth?

8 sits in the ones (1) column.

5 sits in the tenths (1/10) column.

4 sits in the hundredths (1/100) column.



Now the four tells us that the number you've mentioned
has 4/100 in it.

0/100 < 4/100 < 10/100

But, 4/100 is closer to 0/100.

Therefore, 8.54 rounded to the nearest tenth is 8.5.

because 54 rounds down to 50 rather than up to 60 (because it is less than 5), it will remain as 8.5
