Question

Which expressions represent the distance between 4.7 and −11.2−11.2 on the number line?

Drag and drop the correct expressions into the box.

Answer 1

Two of them: the second and the fifth.

Distance is the absolute value of the difference of the two points:

|-11.2 - 4.7| = |-15.9| = 15.9

and |4.7 - (-11.2)| = |4.7 + 11.2| = |15.9| = 15.9
