This combined with the number line is to help you visualize how fractions can be represented and how you find their sum.
The rule is move left when the number is minus. Move right when the number is plus.
so -1 1/4 = (4*-1 -1 )/4 = - 5/4
Start at 0 and move left. The number beside - 1 on the number line is -5/4 Put an arrowhead on the line you just drew. The arrowhead should be just about -5/4.
Each mark on the number line is 1/4 away from the next quarter on the number line.
1/2 = 2/4
So since 1/2 is plus, you move right. You need 2 marks right of -5/4. You will find that is at -3/4
