The process of writing repeating decimals or repeating pattern of digits by using a bar is called Bar Notation .
The bar is put above the digits which keeps on repeating after a decimal.
When we divide a fraction then there are three cases .
1) Division comes to end
2) The division does not come to end it goes on for ever
3) The same digits keeps on repeating after the decimal.
The given fraction is 
The digit 54 keeps on repeating So the bar is put over 54
The third option is the right answer where the bar is put over 54.
Answer: OPTION D.
Step-by-step explanation:
The formula that is used to calculate the slope of a line is:
Where 
and 
are two points on the line.
In this case the student finds the slope of the line that passes trough these points:
You can notice that she writes in the numerator that:
So she chose the point 
as and the point 
as .
Then 
and 
in the denominator must be:
Therefore, she did not keep the order of the points the same in the numerator and the denominator.
Answer:
<1=73
Step-by-step explanation:
All triangles add up to 180 degrees!
Add 20 and 87

180-107=73
Hope this helps! :)
