The answer to this problem is 5.
To solve this, you just divide 20 divided by 7.
20/7 = <span>2.85714285714
If you are trying to round to the nearest tenth, the next decimal place (hundredths) is a 5, so you must round 2.8 up one more digit.
Your final answer is that</span> 20/7 = 2.9 when rounded to the nearest tenth.
