Answer
794.0
Work Step by Step
We are asked to round 793.988 to the nearest tenth.
Step 1. Draw a cut-off line after the tenths place. We are cutting off both 8s. They will be dropped.
Step 2. We look at the first digit after the cut-off line, which is 8.
Step 3. Since this number is greater than or equal to 5, we round up the digit in the tenths place by 1 to 10. We write the digit in the tenths place as 0 and regroup 1 to the ones place
Therefore, 793.988 rounded to the nearest tenth is 794.0.
