Here is the fourth one.

Question

Use the drop-down menus to label the points on the number line.

 

Point A is at -2 2/4-1 2/4-1 1/4-2 1/4.

 

 

Point B is at -2/4-2 1/4-1 1/4-3/4.

 

 

Point C is at -3/41 1/4 3/42/4.

 

 

Point D is at 1 3/42 1/41 2/4-1 3/4.

 

Answer 1

The small divisions are quarters.

Remember we have to count to the left of zero for A and B and to the right of zero for C and D.

Start at A to the left of zero, so A is negative: it is 2 quarters to the left of -1 so 2/4=1/2 and A must be -1 1/2.

B is between 0 and -1 and is 3/4 to the left of zero at -3/4.

C is between 0 and 1 at 3/4. C is the opposite of B.

D is between 1 and 2 at 1 3/4.
