Hi there!
To add fractions there are three simple steps:
1. Make sure the bottom numbers (denominators) are the same. → In your case you're all good, both your denominators are 8.
2. Add the top numbers (numerators) and put that answer over the denominator :
-3 + 7 = 4 → 
3. Simplify the fraction (if needed). → In your case, you do need to simplify your fraction :
Divide both your numerator and denominator by 4 to get your simplified fraction :
4 ÷ 4 = 1
8 ÷ 4 = 2
Your simplified fraction is : 
There you go! I really hope this helped, if there's anything just let me know! :)
Graphs are used to put numbers in a visual form, like a bar graph showing population growth over time. Their advantage is that it helps the viewer understand the situation by seeing it in a easier way.
