Let's round the number 29.15 to the nearest tenth.
Step 1: Identify the place to round to.
We want to round to the nearest tenth. This means looking at the digit in the tenths place and the digit to its right.
In 29.15:
- The tenths place is 1 (the first digit after the decimal point).
- The hundredths place is 5 (the second digit after the decimal point).
Step 2: Look at the digit to the right of the rounding place.
The digit to the right of the tenths place is the hundredths digit, which is 5.
Step 3: Apply the rounding rule.
If the digit to the right is 5 or greater, round the tenths digit up by 1.
If it is less than 5, keep the tenths digit the same.
Since it is 5, we round up:
1 (tenths) + 1 = 2
Step 4: Write the rounded number.
Change all digits after the tenths place to zero or remove them.
So, 29.15 rounded to the nearest tenth is 29.2.
