Answer:
0.143
Step-by-step explanation:
First of all, you're gonna need to know decimal places
0.143
0=ones
1=tenths
4=hundreths
3=thousandths
So now you know that you need to go to the third decimal place
To get your answer you need to divide your numerator (top number) by your denominator (bottom number)
1÷7=0.14285714
You round up the 2 to a 3 because when rounding you take the closest number that isn't being used and if its larger than 5 then you can round up your number
Lastly, you put your answer in the thousandths decimal place
There ya go! Your answer is 0.143
