Are you sure you mean 5.1÷104 and not 104÷5.1
If the first one is right, then perform the calculation (using a calculator)
5.1 ÷ 104 = 0.049038
Rounded to the nearest tenth, t is 0.0 (That might surprise you but here's why)
Look at the 2nd number after the decimal point. If it is 5 or more, then you round up the 1st number after the decimal point. e.g. 5.3698 would become 5.4 rounded to the nearest tenth because the 6 is more than 5.
If the 2nd number after the decimal point is under 5, then you would round down. e.g. 5.3487 would become 5.3 because 4 is less than 5.
Now returning to your question, the 2nd number after the decimal point is 4 which is less than 5 so you have to round down to 0.0
Well, isn't that a happy little math problem we have here! To divide 5.1 by 104 and round to the nearest tenth, you simply perform the division which gives you approximately 0.05. Remember, it's all about enjoying the process and not worrying too much about making mistakes. Just keep practicing and you'll get better with time.
