How do i round to the nearest tenth

Draw a number line from 10 to 20. The numbers on the left half of the line (like 13 or 11) are closer to 10, so they round to 10. The numbers on the right half (like 16 or 17) are closer to 20, so they round to 20. Rounding with decimals can seem confusing, but it's really the same process. You could relabel your number line as "0.10, 0.11, 0.12, ..., 0.19, 0.2" and you'd have a number line for rounding to the nearest tenth.

Example 1: Round 7.86 to the nearest tenth.
 Example 2: Round 247.137 to the nearest tenth.

Example 1: In the number 7.86, the 8 is in the tenths place.
Example 2: In the number 247.137, the 1 is in the tenths place.

hundredths place is 5, 6, 7, 8, or 9? If it is, "round up" by adding 1 to the tenths place digit. Get rid of all digits after the tenths place, and you have your answer. Example 1: The number 7.86 has a 6 in the hundredths place. Round up by adding 1 to the tenths place to get 7.9, removing the digits to the right
Round down if the hundredths place is 4 or less. Is the digit in the hundredths place 4, 3, 2, 1, or 0? If it is, "round down" by leaving the tenth place as it is. Just remove any digits in the hundredths place and further to the right. Example 2: The number 247.137 has a 3 in the hundredths place. Round down by removing everything past the tenths place, to get 247.1.

i hope i was helpful

•You round right to
left

•5 and up,goes up
•4 and under, goes down

Examples~

.728= you round the 8 up to nine

.729

So if it goes up then the next number goes up to

.739

It really depends on how many numbers you need
